Yea it is possible I went from total panic if someone said something to me to speaking out publically against child sexual abuse without taking medication and without seeing a therapist for it. How I did it was one step at a time. first I started by giving people a quick smile if I was picking up the mail and so on and then when that became habit I started saying - "good morning" and "Hi" to those I recognized in passing. then after that became habit I would have very short and quick conversations by saying "Hi how are you today" and letting the other person do ost of the talking. you would be amazed by how much other people like to talk about themselves just by my saying hi how are you I learned so much about my neighbors and others on my street. From there is was all ok and just a matter of talking a little bit more each time.

Hang in there
