Should I stop breastfeeding?

Long post ahead; I appreciate anyone who reads all this and weighs in. I’m so torn. I have IGT (insufficient glandular tissue) and have to fight to keep any kind of supply as it is, even with pumping. And pumping makes me so depressed I just want to die. My son (2 weeks old) was born with tongue/lip ties and a cleft palate. We have to supplement use nipple shields and even then, his latch is so poor and my supply so little, he barely gets anything from me. We can release the ties but his cleft surgery isn’t until he’s at least 6 months, and that’s the only thing that will fix his latch. My older child (2yo) just had to have a surgery that has left him in need of physical therapy, so it’s a little like having a 30lb newborn in terms of independence. I also struggled to breastfeed him and it gave me severe baby blues before we finally settled on comfort feeding and formula the rest of the time. Breastfeeding is so important to me because of the relationship and how much it helped my firstborn settle at night, but it feels like everything is against us making it happen. And if I’m having to use shields and still having trouble, it’s not very convenient for overnight either. I stress about it so much because I love it and feel like I need it just as much as he does. I don’t know what to do or what it’s worth to struggle for the next 6+ months to make it happen. Thoughts?
