Postpartum depression?

FlowerChild🌻🌺🌼
Has anyone ever had this if so can you explain what you felt like and how you got through it? I had my dd 8 months ago and the last three months I just feel so depressed. Almost to the point I think my sweet baby would be better of with out me bc its only gunna be a matter of time before I disappoint her.. I feel so worthless and like I'm not good enough for anything. Any help would be nice! Also I got pregnant after my dd but it ended in another mc.. Maybe that's it idk..
