A lot of people with anxiety, at some point in time, will back away from people. If my brothers comes to the house here with their kids, I will stay in my bedroom. I don't mind going down and saying hello. But sitting there with the lot of them is not my cup of tea at all. But they know it. They know it is my condition. It is never taken up the wrong way at all. If you can get that kind of understanding going on it might make things a bit easier for everybody involved. That you are not been rude. It is just your anxiety. People can also back away from friends. I am in my 40's now. When I was 20 I would say I had around 50 or so friends. Today you can count my friends on one finger. When my condition was at its worst years ago I let them all go and and done my own thing. I can't say it bothers me at all. I am long since passed that point in time. But things can go that way. So just play it as best you can if you want to keep your friends. Be as open as you can be. If they are good, true, friends they will accept you for who you are.
