I have extreme moods that change rapidly and last maybe an hour or so and then lift. I can have a severe up, down and a "normal" mood all in the same day.

Not having a stable personality/sense of identity is difficult because I will often behave completely differently depending on my mood state.

What keeps my moods stable is trying to find a balance between alone time and time spent around other people. Unfortunately though it often feels out of my control. My aim is to have a flexible social network (any social network would be nice right now) and a job that didn't involve being stuck around people for 8 hours a day.
