Hey!
I have experience in this. I knew i wanted to transition my senior year of high school. I wanted to talk to a therapist and see about taking T, but my parents were not excited by any means about it. So we made an agreement that after my sophomore year of college I could start hormones. That was not a short waiting time by any means.
My freshman year of college I lived in coed traditional housing which frustrated me, especially first semester when i was in a dorm filled with 'not my type of people'. Second semester was better when i switched dorms. Even though everyone one on my floor was female (as opposed to fist semester), we were all really close and they respected my pronouns. Outside of close friends i was seen as a butch female because usually once i talked people would figure it out.
My sophomore year I was in a suite style housing with 3 other girls i was close to. With the suite style housing i had my own room and shared a shower and bathroom with my suite mates. This helped ease some of my stresses. That year i also joined a fraternity (only two people knew and i don't exactly know how that happened pre-t, but it did) I didn't really go to all of the events or hang out with the guys all that much during my sophomore year. It was mostly out of fear that they would figure me out. Also, that year in all of my classes except for my foreign language class (because it was only 20 people) I was seen as a guy for the most part and i deleted all public photos of me being female on social media and changed gender to their on FB to appease my parents.
At the end of the semester I started T and it was amazing. My job acted like nothing happened which was nice and when i returned to school for my junior year (my current year) the guys in my fraternity didn't mention anything about the voice drop or differences (might have been because i hadn't seen them for 3 months). There were a few people that asked if i was sick but i told them i started hormones and they had "oh yeah duh" moments and that was it.
Now as far as my living situation goes i'm living on a traditional male floor and we all share a bathroom and showers. I haven't had any issues other than initial nerves at the beginning of the semester of being found out, but its been fine. This year i have been more social and the guys in my fraternity are my best friends. It's really nice to get some of that male socialization i didn't really grow up with. I recently got my top surgery over break and i'm excited to be apart of swim club next school year on the boys team. Things are really looking up and i have had a great transition. I go to a big 10 school so there are about 25,000 students that go here. It's made my transition a little bit easier than what I suspect transitioning would be at a school of 2,000.
Hopefully that helps?
