Do you get out around people very much ,d?
I have a son a little older than you who was a JW very briefly. His work schedule is such that he has to make an effort more than most to get out among PEOPLE. When he doesn't make himself do this, he gets anxious about EVERYTHING--women especially.
The less secure you feel about just knocking about with others the more you will feel in a spot light when you talk to a woman.
There are places, as has been mentioned before, where you can find others with interests related to your own. Libraries sponsor events, meetings, presentions,discussions etc. where you will run into others people--without pressure.
Make yourself go where there are people.
And if it is really a problem for a long time--and your fear and sense of dread around women persists--get a bit of counseling. It will help. I know people that have done that too.
