I'm sorry for your experiences and your pain PuckLuck.
I think, in early recovery, we have to learn how to navigate the emotions we've been numbing with alcohol. Talking to the lady at the gas station felt awkward, but it was a start. You can get more comfortable by having those kinds of interactions and you will be able to figure out how to relate to people. I doubt that you are cold, but that you need to get in touch with the emotions that have been buried due to bullying, parental attitudes and drinking.
