I don't know where else to ask about this, sorry if it doesn't fit this subreddit...

I've never had this before, but for a while now, every day I get random bursts of energy, maybe adrenaline rushes. I feel like energy builds up in my chests then bursts, making me unable to sit still. It makes me wanna shake my head or limbs, or jump or hit myself, stuff like that. I think that's the best way I can explain it. And if I don't I feel kind of nauseous in my stomach, until I move around and release the energy.

And then at the end of every day, around midnight, I get extremely tired suddenly, fall asleep, wake up after a couple of hours and then I can't go to bed until early morning.

It's weird, and I don't know what to do. I rarely drink coffee so it can't be caffeine making me restless. I feel like it's getting worse, like I'm getting more and more restless. A moment I'm calm and fine and the next I want to jump around and run a marathon. 

Anyone have any advice? Idk what to do...
