I've always been really shy, but it's almost like I'm mute until I have permission to speak, and then I can be quite chatty and really enjoy talking to others. For example, in a meeting I can never just pipe up and say something, I'll sit there in silence with a smile even when there's something I want, or even need, to say.
As soon as someone directly addresses me, the wall comes down and I can happily chat away. It's so bizarre, I can't explain it or seem to do anything in the moment to help myself find my voice.
It's similar with things like going for lunch with colleagues. The whole team (around 5-10 of us) tend to go for lunch together when we're in the office. It's pretty much presumed everyone will go to lunch together (i.e. there's no - 'do you want to join us for lunch?' but it's more 'c'mon let's go to lunch'). If nobody directly asks me to join I won't, I'll stay sitting in the office and then once they've all gone I'll go off on my own and have lunch somewhere else by myself.
It's making me quite tearful to write this as it sounds so sad, but also kind of pathetic and helpless. I don't know why I'm like this :(
