Musica, welcome to PsychCentral!

I would practice talking to people like store clerks and people in waiting rooms/lines you are with but don't know. Talk about the weather or when they get off work or what they are doing "this" weekend, etc. The more practice you get, the easier it will be to just start talking to anyone instead of worrying about what to say. It will help shift your behavior to "doing" instead of "thinking".
