Help Tonya keep her remaining sight

My name is Tonya and I have been on a 12yr long journey fighting vision loss. The doctors have determined that my immune system is the cause of the vision loss and have diagnosed me with Ankylosing Spondylitis, Chronic Uveitis, Macular

Degeneration, Psuedotumor Cerebri and most recently Neurological
 Sarcoidosis. I have been given every type of TNF Inhibitor (biological agents) but no progress. The doctors also need to be careful because I have had the JC Virus and a lot of these drugs may cause a complication with this virus and lead to brain damage & death. The doctors have now decided that the best course of treatment (in addition to prescribed pills) will be to try a chemo therapy drug called Rituxan. This drug is still in trials most auto immune diseases; it's currently used for rheumatoid arthritis and non-Hodgkins lymphoma among a few other cancers. This is a very expensive treatment, $13,000 per treatment. I do have insurance but my portion of the treatment is 15%. I have to have at least 3 rounds (2 treatments per round). I know that there are grants through the drug company and other non profit foundations but these grants are diagnosis specific. I did qualify & received 1 grant for $1,500 but did not qualify for any others. I am single & on medical disability so am limited in funds. I can no longer drive but have family members that are living & willing to drive me to all my doctor appointments (even the ones in a different state every 6 weeks). So I have a great support system & couldn't have done all that I have done so far. I know the Lord has a plan for me (even if it is going blind) but I want to fight as long as I physically & financially can. Please know that any help given will go 100% to my medical costs & nothing else. I have attached some pictures of the eye injections I get every 6 weeks to help with the eye swelling as well as the injection of the implant. If you have any questions, comments or concerns I will do my best to answer them. You can email me or send me a message on Facebook. Thank you for taking the time to read my story.
