HELP! My baby doesn't want me (my milk) anymore 😢

Ok so, for the past maybe 5 days my daughter would not latch at all! I am (or was 😔) a breastfeeding mama. I exclusively breastfed up until I had to return to work, my daughter was 2 months at the time so essentially, breast milk is all she knew for 2 whole months.

Unfortunately, I had to supplement with formula upon returning back to work because I would never pump enough breast milk to leave with my S|O while I work. I DID NOT want to put my baby on formula 🙄. So my daughter was slowly "weening" off of my breast. It got to the point where she would only nurse in the middle of the night & early morning (i work midday|evening). I'm guessing because she would still be half sleep & couldn't tell the difference between my breast & the bottle. I still tried to nurse as much & as often as I could, but she didn't really want my breast during the day. She'd pick & choose when she wanted me or the bottle (the bottle got chosen most of the time.) In order for her to nurse, I would have to stand up & walk around w| her while I fed her. I would also pump at work, but my supply was slowly lowering. I'm positive I don't produce as much as I used to which is another problem cause that makes it even harder for her to nurse because not as much comes out & not as fast as the bottle.

Anyway, so for the past few days she hasn't latched AT ALL! ⁢ makes me really sad & discouraged. I will hand express milk & put it on her lips or tongue & she still won't latch. I wanna breastfeed her up until maybe 8-10 months. So is there anyway I can build my supply back up enough so that she'd want me w|out having her nurse? because she won't. I kno there's drinking enough water, having a healthy diet & nursing (supply & demand). Will pumping vigorously help? Lactation cookies? I jus don't want to give up. I don't want this to be the end. It's only been a few days so I feel there still may be hope. Please help.

Signed,

Desperate Mama
