I think i may need help

I have been suffering from depression and anxiety for years but after having my beautiful kids it hasn't been that bad big of a problem. I tried to kill myself when I was a teenager and was all hopped up on meds. Never thought I needed any of that again until now. I have no idea what's going on besides a breakup that I knew wasn't going to work anyway. But I can't seem to stop crying and feel so worthless. My body and head are numb. I can't get out of bed at times. I am worried I may hurt myself again. And I can't take care of my children if I'm like this. I'm so scared idk what the best solution would be right now
