You need to be seen at a tertiary medical facility if there is no one in your community who is able to help. This is something that a primary care doctor can do, and most university programs have a stream lined process for making that referral usually with a phone call. Your nutritional status does need to be buffed up before you could be considered a safe surgical candidate - but that can be done through your feeding tube or PICC line. rjbj is also totally correct - you need someone to advocate for you - this is going to take pit bull persistence and tenacity, and I can't imagine that at 85# your body has the fuel to spare to do all this on your own right now.
If you are unable to get a referral, as a last resort only, you could just present yourself to the ER at a bigger medical center, and they can refer you to the appropriate specialist(s). You are going to have to be persistent- this is not easy for you, and it is not going to be easy for whatever doctor(s) get involved with your case, because things have already gone wrong. Good luck to you.
