I feel like giving up

I’m to the point where I want to give up breast feeding. My daughter is almost 10 months old and I just feel like I’m not producing enough. My boobs ache all the time and when I talk to lactation consultants, they don’t give me any advice other than don’t give up. I don’t know what to do. I work and have to pump but when I’m home, I breastfeed. I pump for 20 minutes every 3 hours and only produce 12 ounces on a 12 hour period and that’s all I can give to her at night when she is with my mom😭 I go to work by 6 and she drank the 12 ounces by 1:30 tonight! Please help. I don’t know what to do. Part of me knows I shouldn’t give up since I only have two months left but the other part is just done and over it...
