I meant to reply to this ages ago but I guess I forgot. Sorry @Ben-RO!
Anyway, Do you find yourself not stressed enough? Or too stressed? Or something else?
I tend to find myself too stressed most often, although there are unproductive times when I am not stressed enough. Generally, when I'm too stressed, I feel as though there's too much on my plate, and when I sit down calmly and try to tackle it, I realise that I can manage it much better than my over-active brain was trying to tell me I could.
What things do you do to get back to the right amount of stress?
When I'm really stressed I'll clean my room, because I feel like the mess outside my head kind of mirrors the mess inside. If that makes sense. And after I've cleaned a bit, I can usually make a cup of tea and write a to-do list, which are other things I do to lower my stress levels. I also try to go for a walk (sometimes, a run), to burn off the excess energy I might be feeling. Or I'll force myself to sit down and focus on something that has absolutely nothing to do with whatever I'm stressed about. e.g. do some colouring in, or read some fanfiction.
