is it possible to get rid of social anxiety?? :(

I just graduated middle school, and I'm going into highschool after summer break. I'm tired of living with this disorder. I've lived with it for years and I'm just wondering.. is it possible to get rid of it?? I want a decent highschool experience. I don't want to be popular but I do want friends. just a small group. I don't want school to go how it did in middle school. I had no friends and the days DRAGGED. if it is possible to get rid of, how do I get rid of it on my own? I have a mentor and a therapist but neither are helping me. I struggle with talking to kids my age, and my mentor just makes me pay for stuff at stores. I'm too afraid to talk about stuff with my therapist because I'm afraid if I say the wrong thing I'll be sent away again. idk, please help :(
