I Have Very Bad Anxiety, Panic Attacks All The Time,

I have very bad anxiety, panic attacks all the time, sweaty palms, short breathing, headaches, and dizziness. Im not sure how to address this to a doctor in real life, because I get way too anxious, and I do not know what would help me. I've heard of Xanax before and I have friends with the same disorder (Not sure if that's what I have) who say it helps. What do you think?
