People say I have social anxiety/phobia, but I like to say there is a cause. I have big problems talking, usually along the lines of not being able to find the words to say. I do this in small groups, and large groups. I don't like dealing with the frustrations of trying to speak, so I avoid social situations. Not to mention the memories of the ridicule I used to get when I couldn't find the words to respond. I hate, hate, hate being called an idiot.
I have no problems doing things like going to the store because the only person I have to talk to is the person at the cash register. That conversation is so rehearsed I don't have any problems with it. If I am having problems trying to figure out if a product is what I want or need, instead of asking somebody, I go home, look it up, research it, and then go back to the store.
Questions, btw, are the hardest thing for me to find the words for.
