Should I just quit breastfeeding all together this is just depressing... don’t know what to do

My son was born a preemie (27 weeks) spent most of his time in Nicu he’s now 9 months but he’s not 1 until April 15. He stopped latching and it’s been awhile. I spoke to a lactation consultant around last month she told me to keep trying if he won’t latch. I tried everything skin to skin give him cuddles but every time I try he pulls away from my boob and screams. I do not wanna force him as if that would make everything worse. He’s taking solids and I think he stopped latching around October. So I would have to supplement with formula and just pump and pump. I really plan on giving him breastmilk up to a year that’s what I’ve always wanted to do. But with him not latching it’s just I don’t know if it’s possible anymore i don’t wanna dry up so in order for me to not i just keep on pumping even though I don’t really get a lot at all I just give him what I have. I really want him back at the breast but it’s so hard so I’m slowly giving up and just pumping 😢
