I think it is very possible. Stress in the body over flows into different areas.

For example if you break your leg there will be a stress over flow in your limbic system and immune system etc

Stress from lifestyle, food, sleep etc will effect mental, emotional and hormonal health.

Financial stress etc effects all.

When put in a sympathetic state (stress state or fight or flight) the body turns down rest, recovery, repair and turns up hormones and functions needed for fight or flight.

ANY kind of stress effects the whole body. relationship, over training etc

So if you had to run from a lion the stress response would be more important in that moment than an immune response.

What that means is when over stressed the body will prepare for fight or flight over working on cancer cells etc (we all deal with cancer every day - cancer is a SYMPTOM not a cause in many cases in my opinion)

So stress hormones take priority in the body over rest, recovery, repair and sex hormones etc.

It is more important to run from the lion than manage cancer in the body.

We live in a very high stressed society and are in stress over load much of the time.

The air we breath, (and how we breath - mouth breathing promoted a stress response and nose breathing promotes a rest/recovery response - children under about 6 that have not been traumatized will naturally belly breath, rest/recovery, most of us chest breath, promoting stress response), food we eat, water we drink, go go go life style, over exercise, financial stress, relationship stress, long hours of light and artificial light at wrong time etc etc all promotes a stress response (cortisol release for example)

People who eat a low fat diet are fucked (everyones dietary need for fat is different of course) cause fat is basically where we get the building blocks for hormones.

Now stress hormones are first priority.

-So if hormones are made from fat.
-We eat low fat (telling 'God' or 'Mother Nature' they don't know what the fuck they are doing)
-Over stressed
-Stress hormones get first priority!
-the little fat eaten goes to make stress hormones
-not enough to make rest and recovery AND sex hormones (it is amazing the figures of couples that can't get pregnant - kid prob wouldn't be healthy - or that have no drive or can't get it up etc

I don't know if you thing is because of hormones but there is no way, whatever the cause, that it wouldn't effect hormones.

In our society there are very few people with balanced stress/recovery levels.
Feeling stress free is a lack of sensitivity to the body.

If we constantly live in stress it is normal. Experiencing different places is the only way to experience the differences.

It is all relative of course and I have no idea your situation or details.

Just some thoughts ;)

I would consider what may have been going on (maybe on a deeper level) 3 years ago.
