Very long anxiety question, but I REALLY need your help!?

Basically all my life ive been dealing with being painfully shy and had trouble making friends due to this. I always shake meeting new people or I get stuck and don't know what to say. As I got older Iv been SORT of able to start talking to people and such. I'm 17 now, and I've been taking Adderall to help me with school for two years. Its been working but I feel its brung my anxiety back, but only WORSE. I can't talk to people AT ALL with out shaking or talking too low or monotone. So in cl, I just DONT talk, its not that I dont want to, its that I CANT. It's been KILLING me becuase I cant get a boyfriend or friends or ANYTHING and it sucks. So i've been slowly falling into a depression. Coming with the anxiety, Im having a VERY big problem opening up to people. I haven't told my parents or anyone cause I dont want them to feel bad or feel diffrently of me. I don't know what to do, I'm trpped in my own mind. I'm currently about start taking Vyvanse, But I haven't yet. Will that help or worsen it? I need answers NOW, I've been suffering with this problem too long I can't take it.. I'm not an emotional person (which is why I cant date becuase I never come out to tell them I like them, I usually come off as rude) and I prefer hiding my feelings from people so they don't take advantage of me or think im weak. HELP HELP HELP HELP!
