I feel like a failure 😓

Ever since birth I’ve been nursing my lo. I ran into plenty of problems from it hurting to nurse her, to being engorged to finally my milk supply decreasing significantly. I purchased lactation cookies and mothers milk tea but haven’t seen much of a difference. My lo cries when breastfeeding and now she’s having a hard time latching. I don’t want to give up breastfeeding but I’ve given it my all and nothing is working. She’s only two weeks and I want to give her all the nutrients I can but I’m failing . My family is making breastfeeding a big deal so I feel so pressured not to give up but me and baby are both frustrated
