I'm sorry you're in such a bad way and that this has been going on for so long.
I question my "identity" at what my "normal" feelings should or should not be without diagnosis. It's a tough one when you feel trapped under the wheel of emotions.
Are you involved in any activities that engage you in a stimulating way? Going to gym? Belonging to a club of some sort?
I'm just wondering if there's some you can do away from the hum drum of life.
