Struggling... need help

I have a personal therapy, a group DBT therapy, coaching, a couple of friends who support me, I am taking antidepressants... I've been working on my mental health for 15 years... I am 37yo, female. I have a 7yo beautiful daughter. Last year I left my husband, got divorced through a very painful and long process. Then I had a very painful love story (I really want to emphasize that I met this person 6 months after separation and I have never cheated on my husband). And couple of weeks ago I got laid off from my 6 figure job. My ex husband is not paying child support (he doesnt have money or job and is drinking), I dont have family here. I have ptsd, some borderline tendencies in the past, trauma - which I honestly have been working on for over a decade with so many different ways and approaches. I started taking antidepressants only now. Because this last year completely destroyed me. I am barely functioning even with all the resources I have. I dont know what else to do or what I am doing wrong. I tried talking to a listener here in the chat and he just ghosted me.... I have all the bad tendencies of my mind resurfaced again. I am so beyond tired. I cant do basic things. On top of that I feel eternally guilty because my daughter didnt deserve all that... I am afraid we'll be homeless in 6 months... but not even that gives me motivation...
