Advice on writing SAP appeals

I had a really hard abstract algebra course the last two quarters. As a result, my grades went under a little. Now my financial aid has moved into deny status, and I have to write an appeal to receive financial aid. I have a mental health condition that makes school a little more difficult for me, but I am not certain how to implement that into my appeal. I was wondering if anyone had any advice on how to write SAP appeals.
