Thank you all for replying.
I don't think it's hypo because I sleep about 10 hours every night.
I have been on Seroquel for a couple of months, and I didn't have this before. Now I have calmed down a bit, I guess it was just stress because I recently came home from hospital. And I was sleeping very badly just before I left the hospital, so maybe it was caused by some sleep deprivation and stress. I'm doing better now
Thank you all!
