Help raise money for my sick kitty!

Hello! My name is Sofia and my sweet kitty’s name is Vader, in the last 6 months or so he has been suffering with a weird sickness where he is allergic to his own fleas and starts over grooming and chewing at his skin so much that he has developed awful bald spots. I have put him through treatment twice now and he healed up perfectly but then I went to Europe for two months and it got really really bad.. He is in the worst shape I have ever seen him.. We are both currently looking for a place to live so I have had to bring him to the SPCA so he can stay there until i find a stable living situation, they will be sending him to the vet and fixing him up but I will have to pay the bill in the end and because things haven’t been super stable I cannot afford it at the moment.. Anyways, anything would help me and him so I can bring him home to our new home in the next two weeks. 
Thank you for taking the time to read this.
