I'm currently transitioning while in college and the way I see it is this: I dont know these people and by the end of the term i will have forgotten them, so why bother caring what they think?
If anything, before when i was stressing about school, i considered joining my school's LGBT club as a kind of "boost" in confidence to help me feel more welcome. College is nothing like preparatory school, people go there to attend class and graduate and leave... especially in community colleges... Most of the time people show up for class, do what they gotta do, and get the hell out lol. People are actually there because they want to be not because they have to be, so them seeing your transition is honestly the least of their worries. Just be sure to tell the dean or whoever so they can refer to you as your preferred name and pronouns, to avoid confusion or awkward moments where that girl raises her hand after having been called by a male name 😛
