For me, I can get either really happy or completely nonfunctional. I know I lose my interests and self-worth. Look for constantly being tired as you do not want to get out of bed. Even a trip to the bathroom can be exhausting. Introvert type behavior as in not wanting to be bothered by anyone or anything. Lonely thoughts of suicide or self injury are also a couple symptoms. The happy mania is more of an "I can conquer the world" attitude. The feeling of getting everywhere on time and feeling over accomplished may come crashing down the moment that there is a mess-up in these accomplishments. Using medication is a tool to be used to control these thoughts. Not that they need to be used together but practicing and reading up on bi-polar helped me a lot as well. I am hoping that eventually I can regulate my hormone reaction by practicing what I have learned. It is a great start reaching out to others and I wish you the best. Just do not listen to those to that tell you to cheer up they have very little understanding that simply, you really are not able to. Empathize with others too.
