My Husband Is Insecure

He's not insecure in a you can't have friends way. More of a putting himself down all the time way. IDK what to do. My husband has depression and has told me he's thought about suicide... He's in therapy and his therapist has suggested he get on medication. He's worries he will be a zombie and his dad told him only crazy people need meds and he needs to man up. His family is very big on depression isn't real it's just "an excuse to be a pussy". He constantly tells me he doesn't know why I married someone like him. He has a history of self harm and I'm so scared right now. I don't think all meds turn you into a zombie and I don't think he's a pussy at all. His family literally says toxic masculinity is okay as long as the guy is being a man and isn't beating on his wife. But toxic masculinity is destroying my husband because he thinks trying to get help is week. Getting him to agree to therapy was a hassle and he only sees her twice a month. I'm scared I'm gonna come home and find my husband with slit wrist dead on the bathroom floor. I'm stuck on what to do.
