Possible trigger post** depression post

I’m almost 5 weeks pp and I’m not sure if I have postpartum depression? I’ve mentioned killing my self to my boyfriend 3 times now since my baby has been born. I’ve already decided how I’ll do it I just really don’t want to leave my babies and they are the only reason I’m hesitant especially my 3 year old 😢 can y’all please pray for me. I know my post probably sounds like I have postpartum depression but I’ve always suffered from depression, even when I was pregnant my doctor prescribed me sertraline but they were making me have fainting spells so I decided not to take them. Is there a difference between regular depression and postpartum depression?? Please no negative comments
