Re-starting to breastfeed

So a little back story.... my daughter is 8 months old now and only exclusively breastfed for 1 week. Then I couldn’t keep up with her and she was screaming because she was soooo hungry I caved and let her have formula and I switched to pumping so we could mix the two to satisfy her. Well I stopped pumping at 3 months because it became too difficult and now I regret it. I don’t feel bonded to my baby anymore and I want to try and BF again. I squeezed my nipple and I got a few drops of milk out of each breast. Is it possible for me to get a supply again? Is it possible to teach a baby this age to learn to take a breast when the last time they nursed was 7 months ago? Or am I just wishing for something that can’t happen.
