Social Anxiety. Appropriate treatment.

I have been experiencing anxiety mainly during social interactions since high school, and it has become worse over the past few years. It is much more noticeable when I meet people I know, especially girls or very confident people. My symptoms include: Fast heartbeat Hand shaking/tremors Stomach discomfort Feeling uncomfortable while walking Mind going blank and not knowing what to say during conversations I often worry that others will notice my shaking or that I will embarrass myself. Because of this, I sometimes avoid people or change my route to avoid interacting with them. These symptoms are affecting my presentations, interviews, and daily life. I would like to be evaluated and receive appropriate treatment.
