Understanding Bipolar vs. Depression

You’re tired, unmotivated, and disconnected from others and yourself. You wonder if this is depression, and maybe it is. Other days, you may feel like you’re on top of the world. You have a surge in energy, you feel euphoric, your thoughts are racing, and sleep becomes a distant memory. In those moments, you may wonder: Is this still depression or something more?

Many mental health conditions often present with similar symptoms, which can make them difficult to distinguish. Two of these conditions, bipolar disorder and major depressive disorder (MDD), have overlapping symptoms. Both can involve periods of intense sadness, low energy, and changes in sleep and appetite; however, they are significantly different conditions with distinct patterns, causes, and treatment approaches.

At SUN Behavioral Health Houston, we recognize that understanding the difference between the two is essential for accurate diagnosis and effective care. In this post, we’ll break down the key differences between bipolar disorder and depression, explore symptoms, and offer guidance on seeking the right support and treatment.

Bipolar Disorder vs Depression: Understanding the Key Differences

When you’re overwhelmed by emotional pain, it's hard to understand what exactly is happening to you. In these moments, depression and bipolar disorder can feel similar. Both can rob you of your joy, energy, motivation, and sense of self. Both can feel like you’re trapped in the pit of despair, unable to escape. But knowing the difference between the two is an important step toward getting the right help and feeling better.

• Depression, or major depressive disorder (MDD), is characterized by a low mood, feelings of worthlessness, and fatigue. It’s a constant heaviness that lingers, making even the simplest tasks feel impossible. It can strip away the joy from things that once felt fulfilling, replacing it with feelings of emptiness. These symptoms can last for weeks or months and may impact daily functioning.
• Bipolar disorder paints a different picture, one of emotional extremes. While individuals with bipolar disorder experience the intense lows of depression, often seen in MDD, they also endure extreme highs known as mania or hypomania. These episodes are characterized by intense energy and an elevated mood, a lack of need for sleep, racing thoughts, increased talkativeness, and a confidence that soars to dangerous heights. What starts as inspiration can quickly spiral into impulsive decisions, strained relationships, and an eventual plunge back into the darkness.

These emotional swings are what set bipolar disorder apart from major depressive disorder.

Symptoms of Depression in Bipolar Disorder: What to Look For

When some people think of bipolar disorder, they envision the highs – the energy, racing thoughts, and impulsivity. But for many living with this condition, the lows often feel all-consuming. These depressive episodes can be hard to bear, pulling one into a deep emotional fog that refuses to lift. It’s painful and scary, but healing is possible.

Here are the symptoms of depression in bipolar disorder.

1. Persistent sadness or low mood: A deep sense of emotional heaviness or emptiness that lasts for days or weeks.
2. Loss of interest or pleasure in activities: Things that once brought joy may now feel meaningless or draining.
3. Fatigue or low energy: Simple, everyday tasks, such as taking a shower or preparing a meal, can feel daunting.
4. Feelings of worthlessness or guilt: A harsh inner voice may lead to self-blame or feelings of being a burden to others.
5. Changes in sleep patterns: This can include insomnia, restless sleep, or sleeping more than usual (hypersomnia).
6. Appetite or weight changes: Significant weight loss or gain, or noticeable changes in appetite.
7. Difficulty concentrating or making decisions: The mind may feel foggy, making it hard to think clearly or stay focused.
8. Slowed movements or speech: Physical or mental processes may feel slowed down, as if moving through molasses.
9. Irritability or restlessness: For some, agitation may accompany feelings of sadness, creating a constant sense of frustration.
10. Thoughts of death or suicide: In severe cases, when the pain feels unbearable, some individuals may experience suicidal ideation. This requires immediate attention and support.

Similarities Between Bipolar Disorder and Depression: Shared Symptoms and Overlapping Features

When someone with bipolar disorder is experiencing a depressive episode, it can look similar to major depressive disorder. This overlap in symptoms is one reason bipolar disorder is often misdiagnosed as major depression.

Both conditions are marked by prolonged periods of sadness, hopelessness, and emptiness. This low mood can feel unshakable and overwhelming. Another hallmark symptom of depressive episodes in both conditions is anhedonia – the inability to feel joy or loss of interest in activities that were once fulfilling. Exhaustion that isn’t relieved by rest is common in both depression and bipolar disorder, and individuals often feel drained both physically and mentally.

Other shared symptoms include changes in sleep and appetite, difficulty concentrating, and feelings of worthlessness or guilt. During particularly severe episodes, both depression and bipolar disorder can lead to thoughts of self-harm or suicide. These thoughts often stem from wanting the emotional pain to stop, or an overwhelming sense of hopelessness, or that things will never get better.

If you or someone you know is experiencing these thoughts, seeking professional help can be life-saving. Support is available, and healing is possible.

Differences Between Bipolar Disorder and Depression and How to Tell Them Apart

Although depression and bipolar disorder can look similar in depressive episodes, they are fundamentally different conditions. Understanding their differences can aid in finding adequate treatment and support.

The presence of manic or hypomanic episodes is the key difference between the two conditions and the most defining feature of bipolar disorder. These episodes include periods of elevated mood, high energy, and impulsive behavior that do not occur in MDD. These episodes can range from feeling unusually energized and overly confident to experiencing rapid speech, racing thoughts, a reduced need for sleep, and engaging in risky behaviors.

In bipolar I disorder, manic episodes may be so intense that they require hospitalization. In bipolar II disorder, the manic episodes (hypomania) are less extreme but still distinguish the condition from MDD.

With major depressive disorder, individuals experience a sustained low mood over time, without periods of elevated mood. Those with bipolar disorder cycle between mood states, and these shifts can happen over weeks, months, or sometimes in the same day in rapid cycling cases

Differentiating between the two often requires looking beyond depressive symptoms and exploring the full range of a person’s emotional history.

How to Tell the Difference Between Depression and Bipolar Disorder

At first glance, depression and bipolar disorder can look similar, especially during a depressive episode. But the two conditions have differing core characteristics.
