I Have Borderline Personality Disorder

Yesterday I had an episode. I was sitting in class and the teacher was handing out tests for us to fill...Suddenly for no apparent reason I started feeling really depressed, lonely, empty and wanted to die...I couldn't think and I couldn't move...My mind was filled with thoughts like "I'm worthless. Noone wants me. I wanna die..."...Naturally the test didn't fill itself out so I had to hand a blank test in...the same happened on the next lesson...And I kept feeling like that for hours...Today was a little better but there are still traces of those feelings...
