Feeling very very depressed

FTM with a one month old. I’ve been dealing with depression since I was 13. I didn’t take medicine or go to therapy(I tried once, therapist forgot my name and what we talked about and turned me off from therapy.) I handled my depression in very unhealthy ways. Since I was pregnant though I haven’t felt depressed or anything. I actually felt okay. But now it’s like a switch got flipped and all my sadness came back. I feel so low and I hate being around my baby sometimes but I got anxious when I’m not around him. I feel like a terrible mom. I feel like a failure at life. I’ve tried to talk to my husband and family about this and they just don’t understand.

I want to talk to my doctor about it, but anytime I’ve ever tried to talk to anyone about my depression they kind of shrug it off. I’m afraid if I tell my doctor about it he’ll just say it’s hormones and it’ll go away. Or worse, he’ll say I can’t take care of my baby and my son will get taken away.

I just don’t know what to do.
