Bad postpartum depression 11 weeks

Hi guys. It’s been 11 weeks since I’ve had my baby and in the beginning of him being home I remember just crying and crying all the time and I thought maybe I just had baby blues. But now it’s still there and I have days where I just breakdown and cry so bad. I’ve put off getting help because i thought maybe I could get better on my own but I haven’t and it scares me and makes me sad:( I feel like I’m not enjoying my baby and being the best mom I can be. My partner might quit his job to stay with me and help me with the baby even though he takes over after work I’m still so exhausted because even though he helps I only want to take care of my baby boy because I feel like everyone else is doing it wrong. I feel guilty that he might quit his job to stay with me but at the same time I need help and I’m struggling so bad it kills me. Should I feel bad? Should I let him and accept the help and go to therapy? Please let me know what you guys think and did to help your ppd.
