Engorge breastfeeding

Pls help! My Son is healthy and drinking a lot of milk but my breasts are swollen and engorged everytime he wants to latch he can’t hold on to my nipples and it’s so painful for me. I’m finally able to breastfeed but it hurts so much I can’t feed him. I tried pumping but so far my milk supply is really Low. Pls give me some advise on how to double up my milk and how do I get my breasts to reduce swelling so I can finally latch? I feel so depressed. Everytime he wants to latch I can’t give him that and it’s making me feel like I’m losing my bond with him. ?
