Single mom meltdown ,any advice?

Please someone help Ive been a single mom living on my own for 4yrs now of two boys their dad has never been around , and I've had anxiety my whole life, a yr ago I met this guy and we dated for 9months he seemed to like being around me and my kids but then I got depression because he was emotionally abusive but I don't drive or have people to talk to and honestly he helped me out so much but destroyed me inside, everytime I tried talking he would blame me and walk out i put up with it because he helped me but he broke up with me yesterday and I've been a mess ever since, I don't have a job I don't know how to drive I don't own a car and I have two little guys who look up to me and I feel like I've failed and like no one loves me , every year that passes is hard , constantly dragging my kids around the cold winter the hot summer the rainy days they don't deserve this, I feel like giving up I just can't seem to get back up and they shouldn't have to live this hard life because of me
