Social Anxiety

I’ve had social anxiety for 5 years and it is taking over my life. It is preventing me from making friends and socialising. I’m 17 and it’s so frustrating to see everyone going out, having a good time, enjoying their teenage years and I’m just there wishing my life away because I’ve got no one to enjoy it with. I only have one close friend (from high school). I feel so embarrassed when we talk about friends because she’s made a lot of friends from college and she’s got so many experiences to talk about and i don’t because i have NO friends at college. I’m thinking of moving colleges because I want to make new friends and but the main reason is because i don’t like the teachers at the college i’m at. When i am 18 i want to have friends who i can go out clubbing with, i don’t want to be the person sat watching everyone having a good time through the use of social media. I am currently having counselling but it isn’t working - i’ve had these sessions for 7 months now. The doctor has put me on propranol to reduce SOME symptoms of anxiety but that is hardly working - i still feel the bloody same! My doctor won’t put me on anti depressants either because he thinks that i am too young and the anti depressants will interfere with the production of my brain because some bus are still in the growing process. He also thinks that I will ‘grow out of it’, but i’ve had it for years and it’s breaking me apart! I would love to hear everyone’s advice! Thankyou for listening❤️
