Growing up shy

So hi I’m 16 and I’m gonna be a junior in high school this year and I don’t know where else to post this so that’s why I’m here. In this last year I’ve developed severe anxiety. I haven’t been diagnosed yet but have been to a psychologist and given meds ( I don’t take them but that’s not the point here.) I guess people at school think I’m stuck up and I’m assuming that’s because I’m quiet. I’m not nerdy or like an outcast I mean I’m kinda in between almost popular and I have a boyfriend but I’m super shy and like awkward and don’t know how to start convos so I think that’s why people think I’m stuck up. But I’m wondering if people can relate? PLEASE GIVE ME SOME ADVICE CAUSE IM NOT STUCK UP AND WANT FRIENDS I JUST DONT KNOW HOW TO MAKE THEM ANYMORE😭. I dropped some of my friends last year cause my anxiety was bad and I just think people grow apart. So far I only have my bff since middle school and my bf of 8 months. So yes advice please!
