Does flying you to Florida for the weekend enable the mother to carry on with her annual Christmas party? So its not really about you, its about the party.

if it is okay with the college that you get your grades in remotely if necessary (ie if there is indeed a flight delay) then i would not turn down a trip to florida, but thats just me! Just as long as it doesnt jeopardize your job. Cuz they are not thinking about you - you need to think about you.
I would see about getting a white noise machine for your room, rather than always staying at the boys' place. Until you can get a place of your own. Its not really fair to either set of roommates to have to deal with a "loving couple" on a regular basis - or even an extra roommate that they didnt bargain for.
I hope you get your meds soon. Have you tried contacting the companies directly? Sometimes they have programs to provide people with low or no cost meds for a period of time.
At any rate, good to hear from you again
