What you should realize is that the majority of people in the world think like that.
You might not want an answer like this but you can either deal with it (NOT ignore it) and move on or let these things hold you in place.
What I would suggest is to separate your emotions (which are the main cause of all this social anxiety) from reality. When you think of these people you mention, a lot of emotions pop up, clouding your view, causing irrational fears. If however, you will stop and think for a minute, about the reality of the world we live in and the consequences they would face for doing something to you, you will find out that you're pretty safe. You still probably won't like seeing them but you will be able to say/do things they don't like without fear.
Not to be overly analytical but it would appear (at least from the things you wrote) that your family knows about how emotional you are and they're using it to get an advantage over you. Don't let them. It may be scary to stand up to your fears at first but the feeling after you do it is really worth it.
