For me it is somewhat, I fear social interaction because I don't know what to say to most things, I can't think of anything I would want to say yet sometimes and I feel like I should say something to combat the dead end of a conversation I have with almost everyone. When I am not afraid to speak up I will ramble and seem to confuse the person I am trying to speak with and they will give me this weird look like it's never what they expected to hear from me, or try to cut me off quickly, which leads back to fear of saying anything in the first place, then I will give up and say whatever then I will be avoided for a time, then I will give it another go and so on.
