Should I go back to the hospital?

I went to the hospital about a week ago bc I was suicidal. I’ve had sooo much HEAVY trauma happen this year and I couldn’t take it. I thought I was getting better but then the medicine they prescribed just made me feel on edge and I didn’t like taking it so I stopped. I’ve gone through abuse, assault, witnessing drug addiction in a loved one, stalking, public humiliation, my kids’ dad attempted to choke me out at a month postpartum and then ran off, his dad committed and I feel guilty bc it was right after finding out about me being abused, and more in not even a year. I think the final straw was when a dude played with my feelings when I was already also going through yet another harassment situation. I feel like I can’t do anything without something happening to me and I feel constantly unsafe. I don’t want to do this anymore. It’s just getting too heavy. I started drinking and smoking to try to help.
