Have you spoken to someone about the letter? many places will treat human beings as just case file numbers until forced to humanize the situation, when they have a face (or faces) before them that illusion can be broken and we find the empathy compassion and understanding that person has, its not always as we think though. Requested an extension with the promise of looking for an apartment, just to make sure you are not without during the transition.

I would suggest you also put the request in writing to create a paper trail that can be looked back on if need be. If you need assistance formulating a strongly worded letter let me know im somewhat of a wordsmith when i need to be and am happy to help out where i can.
