Struggling

I'm struggling so much to take care of my twins and toddler, there dad is in the picture but won't help even when he's not working he leaves or just sits around and won't help he will text me that they are awake if he's in bed instead of getting up with them, I've asked and asked family for help and no one will help or cares to help I have severe anxiety and depression and it's getting worse everyday their dad has cheating on me and I'm not even sure that he has stopped and I can't get over it I'm constantly wondering where he is when he's not home especially b he takes along time to respond to me if I text or snap chat him sometime he doesn't respond at all I can't do anything right I keep forgetting everything I went to the store yesterday and forgot my wic I'd or lost it idk but the lady wouldn't let me even call to confirm I could use the checks so I had all the formula and stuff for my toddler and babies laying out and had to leave it I got mad and walked out of the store I hot to the car and started crying he got to the car and told me I was a psycho and he wasn't putting up with this shit i told him that the girls used their last can of formula last night and he ended up going back in and buying a can but then he continued to call me stupid and crazy my car is broke down so I can't take myself to the store not that I could alone with 3 anyway but he said he isn't going to take me anymore I have to find a ride he's not dealing with my bi-polar ass anymore I am not bipolar for the record just depressed and have anxiety but he keeps saying I'm bi-polar and tells me to take my medicine even when I already have it hurts so bad I just feel like I can't do anything right and what's the point anymore I just want to die everyone would be better off without me anyway someone better could take care of the kids someone who cam handle it I mean what kind of mom can't handle her kids on her own I just want to die
