Save Chico

I have only used this one time when my  sister died. Now I am desperate to save my baby, Chico. We took him to the vet today and spent our last $45 and he was given a shot and medicines but seems to be getting worse. He is my baby, my bestfriend, my companion, and the only one who loves me uncoditionally. I am single and have only a couple of friends and he is my everthing. It is ripping my heart out to watch him suffer. I am in college and trying to better my lifeto b able to take care of him on my own one day soon. I would appreciate ANYTHING. Thank you.
