do I have an anxiety problem? is there medicine?!

I have a problem similar to cebral palsy where i limp when I walk. All the time I am worrying. A lot of people tell me I worry to much. I'm a freshman in college, and I'm afraid to be in public cause I think people will judge me. It's constantly on my mind. One time I took adderall, and I felt like a normal person, like I wasn't worried about everything as much. Like I let my leg problem and worrying lead me into depression, cause it doesn't leave my mind and I just get depressed on how much i'm missing out on life, cause girls won't like me because of my disability :/ Do you think I have an anxiety problem? What is the next best step? should i try to get medcine for it?
