BNLs is right. If you need to go, just refuse to see them. You could tell them before hand that this is something you need to do alone and a card from them would be ok, but you would prefer no face to face visits. If you told them your wishes before hand, maybe it would keep them from being hurt and help them accept what you want?

I am glad things went better today and I think its great you were able to see that when you snapped at a co-worker it wasn't anything to do with them. That's just awesome! You are doing healthy things, whether you realize it or not. Good going.
