Why Am I Suddenly So Irritable, Anxious, or Not Feeling Like Myself?

By Michelle Clay, FNP

“I just don't feel like myself anymore.”

I hear some version of this from women every week.

Maybe you've always been pretty laid-back, but suddenly even the simplest things get on your nerves. Bad.

You're snapping at your family over things that normally wouldn't bother you.

You feel anxious for no obvious reason.

You cry more easily. You're overwhelmed. You have less patience. Or maybe you just feel…off.

And then you start wondering:

What is wrong with me?

If you're in your late 30s, 40s or early 50s, hormone changes are often a part of the puzzle.

Perimenopause Isn't Just About Hot Flashes

When most women think about perimenopause, they think about hot flashes and irregular periods.

But mood changes can be part of the transition too.

During perimenopause, estrogen and progesterone don't simply decline in a nice, predictable straight line. They can fluctuate, sometimes significantly.

Those hormones interact with systems in the brain involved in mood, sleep and emotional regulation.

That's one reason a woman may begin experiencing increased irritability, anxiety or mood changes even while she's still having periods.

Sometimes these changes show up before she ever has her first hot flash.

Progesterone Is The Hormone I Prescribe Most

When a woman tells me she's suddenly anxious, irritable and not sleeping well, progesterone is almost always the culprit. Which makes sense because it is the first hormone that women begin to lose.

But that doesn't mean:

Anxiety = low progesterone.

It's never that simple.

I want to know what else is happening.

Has your sleep changed?

Are your periods changing?

Are you having night sweats?

Has your stress level increased?

Are you having heart palpitations?

Has your thyroid been evaluated?

Are there other medical or mental health factors that need attention?

The pattern matters more than one symptom.

Oftentimes It's a Combination of Things

This is something I think gets missed when we try to put every symptom into its own little box.

Poor sleep can make you more irritable.

Chronic stress can worsen sleep.

Hormone fluctuations can affect both.

Thyroid dysfunction can cause symptoms that overlap with anxiety.

Blood sugar swings can leave some people feeling shaky, irritable or anxious.

And sometimes anxiety really is anxiety and deserves to be treated as such.

That's why I don't want women assuming that every emotional change in their 40s is “just hormones.”

But I also don't want a woman experiencing a cluster of new symptoms to be told that her hormones couldn't possibly be contributing.

Both extremes miss the bigger picture.

Pay Attention to What's Changed

If you suddenly don't feel like yourself, start by asking:

What changed—and when?

Maybe your anxiety appeared around the same time your sleep fell apart.

Maybe you're suddenly having heavier or irregular periods.

Maybe you're waking up drenched in sweat.

Maybe your libido disappeared.

Maybe you're gaining weight despite doing the same things you've always done.

One symptom by itself may not tell us much.

Several changes happening around the same time can tell us a story.

That's when it may be worth stepping back and looking at your health as a whole rather than treating each symptom separately.

You Know When You Don't Feel Like Yourself

I hear women say this so often that I think it's worth paying attention to.

You know what your normal feels like.

That doesn't mean every change is caused by a hormone imbalance, and it doesn't mean hormone therapy is automatically the answer.

But if something has clearly changed, you deserve to understand why.

Sometimes that means looking at hormones.

Sometimes it means looking at thyroid function, metabolic health, nutrient deficiencies, sleep, stress or mental health.

And sometimes it's several of those things happening at once.

The goal isn't to blame your hormones.

The goal is to stop guessing and figure out what's actually going on.
