I quit pretending with family members awhile ago. It's harder at work, it's not that people don't understand necessarily, I think it's more that they don't know how to deal with you after you tell them. It can make for an awkward association. I don't really have any friends I can talk with about this so I don't know there.
I am sorry you are going through this. I wish I knew how to help, but I don't... Try to hang in there!
