What is DBT Therapy and Why am I in it?

DBT is a form of psychotherapy that was originally developed by Marsha M. Linehan, a psychology researcher at the University of Washington, to treat people with borderline personality disorder (BPD), people who use self-harm  and chronically suicidal individuals

DBT works towards helping people increase their emotional and cognitive regulation by learning about the triggers that lead to reactive states and helping to assess what coping skills to apply in the sequence of events, thoughts, feelings and behaviors that lead to the undesired behavior.

Basically, I am in DBT for the exact reasons DBT was developed and it is used for. I have borderline personality disorder, I use self-harm, I have chronically been suicidal and attempted suicide multiple times. For me, life is a miserable experience and is difficult. I am chronically unhappy, and do not know how to find happiness, do not know how to cope in life with stress without seeking out harming myself because the pain of life is just too much for me to bear. No one gets it. No one gets the pain in my soul. No one gets the pain in my heart.

I have been in DBT since the end of June 2014 and I am still not sure how I feel about it. I don't deal with change very well, I am temperamental.  I am mental illness. I live in darkness, I am lonely, I am just what I am.
