Emotional Instability Disorder

Sometimes I am on a high Other times on a low I never know what personality i will show. Some days I don't know what's happening to me I don't feel myself but what could this feeling be ? Iv searched for so long It's really draining for me Trying to find answers for this iratic side of me I feel bat sh*t crazy This effects me a lot My days can be hazy My nerves become shot. But when I am good I am high like the sky, Life feels amazing, I chat to everyone passing by Next day I could wake Feeling so gloom It makes me feel like the elephant in the room. So many sides of me It can be tough to relate Who am I? What's happening? Why am I in such a state This isn't me nor who I want to be I just want to be normal Like I felt I used to be.
