I'm 17 with crippling social anxiety. I recently got a job as a cashier as an attempt to break out of my shell a bit, but every interaction is miserable for me and I come home exhausted. I feel a bit more comfortable with older people as they'll be more accepting of my incompetence but when having to interact with younger people I always end up cringing at myself. Do I just have to wait for it to get more tolerable? Will it go away by itself with age?
