Engorgement help

Am

My LO is two weeks old and one of my breasts has severe engorgement to where it’s making my nipple flat now. I tried to pump because it felt better and my LO didn’t drain my milk, but it keeps coming back every 2 hours hard and lumpy. I’m already struggling with a difficult latch, and I really want to keep breastfeeding, but I’m struggling ladies. Any tips or tricks? I’ve been heating it, trying to massage it and the shower did absolutely nothing.
