I've had camp so I haven't been on here for a bit but:
I've got orientation week next week, and the week after that classes start.
Something that I think is great about hermit crabs is that they adapt. The shell they surround themselves in is temporary, and they regularly discard them and find new ones that fit them better. It takes time to get to the new match they want, but then they get to experience a whole new environment.
Social dynamics at highschool can be pretty terrible, but I'm glad to see that you've got two good friends. It can feel awful when people make baseless assumptions simply because of having good friends who aren't the same gender; as much as it sucks now, at least it doesn't really matter in any concrete way.
As difficult as it is to reach out, I hope that you're able to get help from a professional in managing your health and wellbeing. It can be hard to find your way to a better space, especially if you don't have a place where you can feel open, safe, comfortable & able to rejuvenate - I wouldn't want you to feel that you had to go through this alone or without that support.
Good luck for your SAC and I hope the difficulties you're experiencing ease soon.
