Wondering if anyone else has experienced this.

I have "high-functioning"/mild depression/anxiety that I manage to mostly cope with med-free. I've never reached a point of severity where I thought "I should get help". and I'm very thankful for that. 

However I do have high and low periods. Low periods where I'm just very irritated by literally everything, not at all productive, and just all around things suck. 

High periods where I am extremely productive, hit the gym every day, read and meditate every evening, limit social media and all around things are great. 

High periods are not forced states and they're just a natural state that my brain decides to enter 2 or 3 times a month. High periods usually last around a week or 2 but seem to be getting longer, as I actively work on my thinking habits and self discipline and gradually improve my mental health over time.

However, I find that once I've been in a high period for about a week I start to feel exhausted by it. It's not as if I'm forcing myself to smile, go to the gym, read, cook, do normal happy things - I'm naturally driven towards doing these things during this time period. But I find that I just get exhausted, and this exhaustion is usually what leads me back into a low period. 

This is just really weird to me. Like come on brain/body, do you want to be happy or not? 🙄
