SAP letter

Hello. I’m currently writing my appeal letter for my academic suspension. Long story short I became homeless after the semester started and then about a month later I lost my job. I tried to keep up but just fell behind and failed one of my classes. I’m confused about the documentation they say to provide. I lived with a roommate who kicked me out because of a her boyfriend at the time didn’t like the idea of a roommate. My name wasn’t on the lease or anything. Just a room I was renting. So do they need to text message or the note she wrote me about kicking me out? Also should I get a letter from my former employer stating I was let go? Will these documents help my case? Thanks in advance.
