I'm not really getting any therapy for it. I take valium, though, which is an anti anxiety drug but of course I still do struggle with anxiety as it can't cure it. I don't believe therapy would help in my case because the reason for my anxiety is something I'd never ever discuss with any therapist. Besides, I'm not not susceptible to any suggestions and I know that I'd just disregard anything they say, and that I'd just criticise them in my head.
Yeah, I'm an introvert now, but I'm also an ex-extrovert - it's just that my personality completely changed a few years ago after some bad experiences I've had.
