I think part of the frustration is that you've continually shown all of the "classic" symptoms of mania and psychosis, things you can look up on PC and all over the internet (and people here have done a lot of explaining) and yet you still insist that you are not manic. I could cut and paste the symptoms here, but it might be better for you to look them up, if you haven't already. Have you?

I still stand by my support of you doing DBT and working with your psychologist because it's better than nothing. I hope learning coping and other strategies will help; you'll be with people with some of the same issues you have. There must be some reason why your treatment team wants you to do this, maybe they see things we don't. Of course they want you to take the Abilify (or antidepressants, I think you've more recently mentioned), but you may as well start with therapy and the DBT.
