Feeling depressed

Megan
I have a history of major depressive disorder, generalized anxiety disorder, borderline personality disorder and anorexia nervosa. Doing things day to day is pretty hard already, but it's ruining my life. I just got a new job and I'm pushing it to the limits by not showing up today because my paranoia is sky rocketing and I'm too afraid of going. I'm feeling really depressed and the stress is making my chest hurt. I hate that I can't do these things for myself, it hurts a lot. I need some advice or some help in some way, I've already been to treatment and had therapy and meds and groups but I don't have time anymore because of my new job. I don't know what to do. How can I calm myself? Or how can I fix things and help myself more and actually live life?
