Hello, /r/legaladvice!

In October 2015, I had the beginning of a not-so-lovely manifestation of an auto-immune disorder, ankylosing spondylitis. At that point, I was employed full time as part of a government agency working with a homeless shelter; I was also (and still am) a full time college student through an online university (don't worry, it's accredited). The symptoms of my disorder that I experience are chronic unrelenting fatigue, chronic joint pain and stiffness, and thanks to the medication I take, I am also immunocompromised. 

Because this disease knocked me on my bum so hard, I was put on administrative leave from November until February, at which point I was asked to resign from my position. This decision was based on a doctor's note stating my likelihood of recovery to the point of being able to work full time was next to none. Rather than firing me, they asked me to resign. I did. Whether or not that was a good idea, I don't know.

Since about December, I have been working on obtaining support from SSI, as I can't apply for SSDI (not enough work credits). Yesterday, I received a letter stating that I was denied disability based on the fact that I am receiving treatment for my disease, and I can still do unskilled labor. They called me "mobility impaired" because I now walk with a cane.

I am not physically well enough to regularly leave my house, and being immunocompromised on top of the pain and fatigue is very stressful. Additionally, I'm only able to succeed in my schooling because of the online format. I do my work from bed. :(
<bot>: Painful autoimmune disorder kicking my butt, was denied disability because I can still do unskilled labor (according to the government). I disagree. I was given 60 days to appeal. Is it worth it?
