The first semester of this school year just ended, and after finals, I have to take Gym. Weight training - I signed up for that class specifically to gain muscle. So, hopefully it works.

My problem is changing in the girls' locker room.

Nobody knows I bind, and even if they did, it would still be weird to take my shirt off in front of a bunch of girls, you know? So either, I wear a bra and don't bind for the rest of the school year - which I would probably not be able to handle and it would stretch out all of my shirts.
I could always go into one of the bathroom stalls that they have in the locker rooms, but we don't always have the time for that and sometimes girls take up all the stalls.
I could wear like, a tank top over my binding, which would hide the ace bandage but my chest is still noticeably flat and my friend, who planned to take this class with me and has seen my boobs and doesn't know I bind, would possibly notice.
>< I don't know what I should do.
