My mind is all over the place. Sometimes I feel so down and awful and hopeless, like life is pointless and nothing will ever change, I cut occasionally and have considered suicide, I just feel so low and I struggle to sleep and often become very withdrawn. I thought it might just be depression but then other times I am out of control, I feel on top of the world and confident, I get energetic and impulsive and can't sit still or concentrate, I also become talkative and end up babbling nonsense. I get irritable and angry often and end up doing or saying things that I don't mean and is totally out of character and gets me into trouble and I feel bad for doing this which often leads to being sad again. If I get so upbeat and out of control then I can't be depressed too can I? I'm confused. Please Help me.
