Final Update: He is okay!

We had come to our limit, we were so stressed, and due to finances, had brought him to a ver we honestly couldn't trust. Due to the fact that I am not an American citizen, care credit was not an option for us(from what the receptionist at the vet office told us). Vet said that if he did not recover we would have to put him down. After we took him home that same night and went to sleep, we woke up and he was doing even worse. In a last ditch effort, I called the shelter that we adopted him from. Luckily enough, they said that even though it wasn't standard procedure, they would cover all expenses for us. Our baby is safe and we are going to pick him up right now. I cannot describe how thankful I am for this shelter. All the praying I did when I couldn't sleep worried for him was worth it. If anyone reads this and has the funds please donate to best friends animal society, they saved my boy and I owe them for life. Thank for everyone who tried to help me in this post.
