Sometimes I feel that when I'm extremely happy and excited about something, it doesn't come without a little mania. To me being truly happy feels surreal at times, I feel it doesn't happen enough and when it does it comes with racing thoughts and bouts of energy. I don't get truly manic, but I feel a difference in my mood.
Is this how happiness feels and I have forgotten or is it being a bit manic?

For example some nights ago I went to bed in a good mood, woke up at 2am and for over an hour was wide awake with racing thoughts. I wanted to get up and write, but I knew I had to sleep, I only fell asleep because I took Clonazepam.

Can anyone relate?
