trans | Dorms

I'll be a freshman in college starting this Fall. I realize now that I need to send in my housing forms in the next couple DAYS, because the office has to receive them by June 30th.

I'm guessing I should write some kind of letter to the housing office about being trans, requesting a single room...etc. Has anyone written/sent a letter like this before? If so, does anyone have a sample I can see? Also - does anyone know of any resources I can send along?

I'm worried that any explanation I attempt to give will just further confuse them. I need to figure out the most simple way to explain the situation that will convince them I can't be roomed with a random and unsuspecting girl. I don't know if they have had to deal with anything trans related before. I know that the the college is pretty accepting overall, but housing could be a lot different.

Thanks for any responses.
