11 Ways to Know Someone is Emotionally Unstable

There have been moments in my life where I’ve felt emotionally unstable. It’s natural to face struggles and have emotional outbursts or periods of sadness.

Having emotional highs and lows is part of life’s challenges, but it’s different from being emotionally unstable.

When someone is emotionally unstable, their reactions are often extreme and unpredictable. While life with them may never feel dull, it’s a sign they’re dealing with deeper, more serious issues.

Emotional instability is often linked to personality disorders but can also arise from depression, trauma, or anxiety.

The key point is that emotional instability can be a symptom of something more profound. In such cases, professional help is essential. It’s not something you can manage on your own.

This doesn’t mean emotionally unstable individuals are bad people, but it does mean that being around them can be challenging.

You’ll likely face difficulties, especially if you don’t fully understand the reasons behind their behavior.

Recognizing the signs of emotional instability can help you approach them differently and guide them toward getting professional help, particularly if they’re struggling and unsure of what to do.

By spotting these signs, you’re already taking a step toward helping them get the support they need. So, let’s not delay. Here are the most obvious signs to look for if someone is emotionally unstable.

# They’re unpredictable

You never know how they’ll react, whether it’s good or bad news. Will they stay calm or have an outburst? Their responses are unpredictable. If their reaction is out of place—like laughing inappropriately or getting angry for no reason—it’s a major red flag.

# They make impulsive decisions

Emotionally unstable people often make decisions based on impulse. They struggle with emotional regulation and problem-solving, which leads them to act rashly and without much thought.

# They’re very moody

This isn’t just being grumpy when hungry. Their mood swings are extreme, like a roller coaster. They can go from being furious to depressed over the smallest things. If this happens often, it’s a sign of emotional instability that needs to be addressed.

# Their relationships are unstable

You’re not the only one confused by their behavior—most of their relationships seem unstable. If their friendships tend to be short-lived and end dramatically, it could indicate emotional instability.

# They lack consistency

They don’t have direction or stability in their life. Their emotions are unpredictable, which makes them seem inconsistent in their actions and behavior.

# They feel entitled

Emotionally unstable people often believe the world should cater to them and their needs. If their extreme behavior is paired with a sense of entitlement, it’s a clear sign of emotional instability.

# They can’t calm down

Once they’re upset, they don’t process their emotions and move on. Instead, they let their anger simmer and hold onto it for days, especially when facing minor setbacks.

# Family background

If you learn about their family, you might notice patterns. Often, if their family is dramatic, they’ve picked up these behaviors from them.

# They lack empathy

They’re quick to get upset when it concerns them, but when it comes to others’ issues, they don’t show interest or support. Conversations tend to revolve back around them, showing a lack of empathy.

# They can’t control their emotions

Most people can regulate their emotions, but emotionally unstable individuals struggle to do so. They lash out in the moment and have difficulty managing their feelings, making them unpredictable in how they express their emotions.

# They’ve had on-and-off relationships

They’re often in unstable, on-again, off-again relationships. Their partner may feel like they’re walking on eggshells, trying to keep them happy. Emotionally unstable people tend to struggle with maintaining healthy romantic relationships.
