Do I have social anxiety disorder?

I am afraid I might have social anxiety disorder. I am not a very timid person, but I feel uncomfortable if I am the center of attention, such as speaking in front of a large group. I turn bright red and begin sweating and I can’t keep eye contact. It doesn’t happen when I am around friends. Because of that, I try to avoid those types of situations. My mom was diagnosed with OCD/schizophrenia. Is it a possibility that I can have this?
