Social Anxiety Background
Social anxiety has affected me since I was in elementary school. While it was triggered initially by a traumatic experience, it is something that runs in the family and I certainly had a predisposition for. Some examples of how it manifested itself over the years: avoiding certain types of social situations and friends, avoiding public speaking, avoiding the opposite sex completely, hiding in the library during lunch, the thought of just walking down certain hallways at my highschool terrified me, fear of being around large groups of people, fear and avoidance of going to parties or social gatherings, etc. My social anxiety started to get severe when I dropped out of college after one quarter because of my social anxiety. That's when I started to get uncomfortable just leaving my apartment and hit "the bottom" so to speak. Through treatment with group cognitive-behavioral therapy (CBT), Eye Movement Desensitization and Reprogramming (EMDR) for mild Post Traumatic Stress Disorder (PTSD), and medication I've been able to live the balanced life that I value and form healthy friendships and relationships.

Toastmasters is similar. You have the opportunity to speak publically and also participate in "table topics", which is a form of improv where you speak about a topic or answer a question.
