Hi Neirin, I'm sorry you're struggling right now
But you know if you can't deal with being around other people.......there's no point in talking to anyone.........you can always hang with us. Maybe you'll feel a bit more "comfortable" talking about the details with us anonymously, but no pressure here, If you want to talk then that's fine, we're here for you, but you don't that's fine too.
And IRL.........sometimes it can be a bit much behaving "as expected" if you're having a hard time, or having people "probing"/having to fend them off...........so if you need a bit of space that's understandable. Just try not to cut them completely out, hey?? Maybe more limit your time with them, because like you said they do care.
And you know, if they care maybe some of them would be OK with a simple "explanation" that you "have a lot going on, feel "down", really don't feel like talking about it, but just need a bit of comany and to be doing something". I'll leave that thought with you though......
And while you've nothing to do.........is there anything particular you do/could do to "let off steam" or "escape"?? e.g. go for a walk, a run, to the gym, go to a swimming pool?? Anything??
And with classes starting in April..........just wondering if you could get hold of a syllabus (??)/what they'll be covering in the classes, so you could do a bit of reading ahead of time, get a "head start"????
And just a thought.......to keep you busy ............what about voluntary work??? I know the "people thing" might be tough, but I'm thinking more on the lines of helping out at e.g. a pet rescue center, if you have one anywhere near you. Animals are relaxing centering, "therapeutic"for some people. Still if not right now, maybe a thought for the future???
But anyway, again........if you want to talk we're here for you.
