What’s wrong with me??

I hate this feeling. Down and not quite sure as to why. It seems the cycle never ends. So tired of it. I felt good for a lil while and now my moods cycle faster than than ever. One min I’m ok the next I want my life to b over. Don’t know what to do. It’s late at night. No one up where I live. No one to talk openly to. Feeling frustrated. Grr
