People Phobia

Not necessarily agoraphobia (I can shop on my own in the St. Louis Galleria mall), but I don't like being around people. I'm not sure when it started, or why (I come from a HUGE family) but I noticed that it has become a problem today. As you know, it is Memorial Day. I found that the get together with my mom and step dad is much larger than I anticipated. My palms have yet to stop sweating and my stomach is rolling..

See, I have certain people I prefer to be around. I don't like being crowded, touched, or bombarded with questions.

Is this something I should bring up with my anxiety therapist tomorrow or is it hormones (monthly is on her way)? Thanks!
