I remember feeling this way even tho I have no physical reasons to do so (that I know of :)), and I still do even to this day, sometimes feel awkward in groups of people. I think there are many people you know that feel the same but just don't show it. It's not the best idea to retaliate as that will just make things worse. Every adverse thing that you handle in the right manner will return to you as a blessing. Do you study scriptures along with your prayers? If not, give it a go.
