I had a nervous breakdown when I was 12. I can tell you as much as I can remember about how I felt. For one, I was rapid cycling, I remember being hyper, irritable, depressed and angry all at the same time. I was overwhelmed with sadness and anger I just felt like taking my life was the only way for me. My mother came in the room and I began screaming at her and hitting her, until she finally pinned me to my bed and tried to calm me down. Most I can say is it feels like you are seriously losing your mind and there is NO hope left, no hope that you can SEE and everything you think is totally irrational. At least it was for me.
