Cant do anything right.

I cant seem to make anything go right in my life. Everyone says im a good person but everything falls apart. I work two jobs and trying to get back into school. But my relationship seems to always have major downs. And im constantly being blamed for everything that goes wrong. I have lost so much in my life and feel like i will never be anything or worth anything. I have tried to kill myself numerous times and never can seem to finish it. I have alot of mental health issues depression, anxiety, borderline personality disorder. And who knows what else. I just cant make things go right for me and am always blamed for everything that goes wrong. I feel i shouldn't be here alive anymore.
