Disturbingly high emotions that last maybe a week, two weeks at best? Then burn out. What, why, and how do I manage it better?

As of maybe the last several months, it's become common for me to have a string of really good days. But they don't last.

And when I say really good, I mean REALLY good. I'm on my A game, I'm confident, I'm social, I'm hilarious... yeah I still have a low hum of depression/anxiety in the background but it's very easy to manage.

However, it's not always easy to manage these good moods and I can get so swept up in it that I accidentally burn myself out - it's like my brain short circuits and forces me to shut down.

Recently I had about two weeks of very high emotions and was the most social I'd been in a while. I got to a point where I could manage it fairly well, but my emotions (good and bad) were still very sensitive.

One day I only slept for 2 hours yet went clubbing the night after because I had so much energy. That has never happened.

After the two weeks, I became overstimulated at work and felt very self destructive, anxious, then so depressed and exhausted that I couldn't sit up and had to take two days off.

Is it just burn out? Maybe I should have socialised less, despite really wanting to? But I don't like ignoring my desires.

Is this something anyone else has had? I just want to understand how it works and if I can do anything to manage it better.

Context:

I'm an adult, female, not on any new meds or new drugs, and may also have autism and ADHD.

People do tend to overstimulate me, but I'm usually a lot better at managing my social battery.
