Breastfeeding depression

I'm. Up crying... I'm 1 week pp and I'm dealing with mastists and possibly endometritis (again) 2nd child. And dealing with an infected tooth. I am in so much pain I want to give up. I tried feeding my baby this morning and realized she started crying..I think my milk is drying up. I feel like a failure. All I'm thinking about is all the antibiotics I will have to go on to get treated for all of this stuff and it really discourages me from breastfeeding.
