Stop breastfeeding?

My baby is a few days shy of 8 weeks old. & she never could get the correct latch. She has a lip tie and possible back tongue tie. Well, the only place around me that accepts our insurance hasn’t got back to us in well over a week or 2. & I’ve been having to pump and feed, but obviously that doesn’t stimulate my supply like it should. I’ve been to the lactation consultant, I’ve taken supplements, I’ve tried oatmeal. I’ve tried to power through the pain, which just leaves my nipples almost purple and cracked. She had a very shallow latch, so it just feels like she’s literally chewing on my nipple. No matter what I do. She gets it far enough in her mouth and her tongue flips up and she looses suction. causing the shallow latch again (she saw therapy for this) but unfortunately they don’t want to do anything until she’s seen for her lip and tongue tie, which obviously hasn’t been possible. Pumping every few hours only give me 2-3 oz out of both breast’s combined (that’s pumping for 30 mins on each side) so I’m already having to give her 2 oz of formula and 2 oz of breastmilk. My question is: is it even worth it? Should I even continue to try? I feel awful for even thinking about it, but I hate having to stop doing what I’m doing every 3 hours, but put my baby down, stop doing house work, just to pump for an hour, then feed my baby, just to do it all again in what seems like an hour. I keep telling myself to just hold out and once we get all of her issues figured out, she’ll be able to latch and it’ll all get better, but now I’m assuming that she’s going to be very cranky as she won’t be getting a lot of milk out of my boobs and it’ll take time to build my supply back up. Not to mention that there’s no guarantee that she will be able to latch. I’m torn. And I don’t know what to do.
