Yeah I definitely have a problem speaking. This wasn't always the case, but with years of isolation and barely speaking to anyone (family even).. it's gotten pretty bad. Nowadays I find it exceptionally hard to express myself since I feel most of my vocabulary has vanished. I guess if you don't use it, you loose it. I'm horrible at small talk, can never start a conversation myself and only respond with short answers when spoken to. I'm sure people find this strange or rude even.
Didn't think it was possible to forget how to communicate/socialize with people, but I guess avoiding it for too long does it.
English is my second language as well, so when I feel like I'm not pronouncing something right, I correct myself, which brings more attention to my mistake.. and then I just feel worse.
I get this. Today I was trying to tell my teacher something so simple but I just kept stuttering and not getting to the point. It was like I couldn't get what I wanted to say out, and I end up sounding incoherent. It happens a lot... :S sorry for posting a really unhelpful post but you are definitely not alone in this.
