I don't know if I should go to the doctor or not but ever since I was about 12 I always pop my fingers and bite my nails when I'm around a bunch of people. I also have poor social skills I always get nervous talking to people I get sweaty and my heart races. I just always want to be alone. I always stress and over think everything I start freaking out over nothing sometimes and I just don't know what to do. It's getting in the way of me living my life. should I make an appointment or does this even sound like anxiety I'm not so sure
