Thanks for the detailed information. Running away from the situation might get you short term relief but what about long term consequences? People will usually have an opinion based on what they see, hear, imagine but that opinion is biased and judgmental in most cases. If you find that you are unable to talk confidently or mingle freely then that's a skill that you can always learn from any organization or work on the reason that is stopping you from doing so. This doesn't mean that you are a looser. At work, you need to be seen, heard and catch attention to be noticed. Everyone has challenges and difficulties in life which doesn't make them any lesser than others.
