Social anxiety ruining my life..

I know for a fact I have social anxiety along with some type of depression for as long as I can remember. Depression started at 12 years old and I’ve been so socially anxious for as long as I can remember. I’ve worked at the same place for over a year with the same people and I still blush and get extremely anxious around everyone. I can’t ever be myself bc I don’t want to look weird. I’m 20 now and want to go to college but I feel like I will never find a career because interviews scare the shit out of me along with starting new jobs and meeting new people. It absolutely sucks and I’m starting to feel hopeless. I want to get help but I’m scared. Has anyone gotten help and on medication and it benefit them? I just don’t know what to do anymore. I hate how my mental health gets in the way of every single thing I do. I don’t know how I’ve coped with it for so long but I just cannot live like this anymore. I just want to be a normal person.
