LOL....yeah, ad1, I know what you mean!
You've gotta love when you go to someone's house for a visit, and you're dealing with "their stuff". You open the door, and realize that their son has smeared something sticky on the doorknob, so you quickly excuse yourself to the bathroom to wash your hands (at least twice). Then, while searching for hand cream in your purse, you rip a fingernail, and realize that you don't have any tools with you to catch the rough pieces. Your hostess offers you a set of nail clippers, which you take into the bathroom with you, so she won't see you furiously scrubbing them with soap and water to get 'other people's germs' off them. Then, while you're in there, drying your hands AGAIN, you find yourself adjusting the hand towels over and over, to make sure that everything is even and symmetrical. Of course, the idea of opening the bathroom door makes you cringe, because you wonder: what if the last person who was here didn't wash their hands? Oh yes, you realize that the last person was YOU! And while you're fussing about all of this, you are also anxious about the fact that someone might notice your anxiety! You are amazed that you can carry on a conversation over coffee, while all of these thoughts are racing through your head, and then you chastise yourself mentally for drinking something with caffeine in it, because you just know that it will rev up your anxiety even more. No wonder you are so exhausted when you leave that you have to fling yourself into bed when you get home, only to worry obsessively that having a nap might mess up your sleep schedule for the next week. Sometimes I feel like I'm my own worst enemy.
