Help Queenie get surgery

hii everyone. recently my cat, Queenie, stopped acting like himself. he lost so much weight and stopped eating almost completely. my older brother took him to the vet where they drew blood & proceeded to send him home with medication for him to gain weight because there “wasnt anything wrong with him”. we thought he might’ve just been depressed because of my brother moving out but upon his 3rd visit to the vet, and more money somehow shelled out for 4 more unnecessary medications, they told us his gallbladder was failing him. Queenie’s in so much pain. when hes not throwing up somewhere in the house he wont eat, he wont drink, he just sleeps or lays still. as of right now we can’t afford to have his gallbladder removed, which is what NEEDS to be done or he’ll die. please donate or even share if you can, every cent is going towards Queenie’s vet bills to make him better. thank you
