More than sad, I just get frustrated that it inhibits the things I do. Such as, whenever anything social is planned - like going out to a bar or a concert - I will plan so that I don't have drive home with people (b/c I'm afraid someone might drink too much and I'll be stuck in the car with them). In fact, I don't like to be in the car with anybody (except my husband and immediate family), or on a bus, train, or plane. Even if nobody is acting sick, if I'm in an enclosed space, I get nervous. So I guess I just get frustrated that I can be as laid-back and flexible as "normal" people about my life.
