I would give anything to see bikeguy in a bridesmaids dress. Post pictures, please.
I would agree that if you take the focus off 'your problem' and issues and take that energy and direct it at your friends special day -you will be successful. Don't give yourself time to think about anything else but the wedding and how you are really there for her...no one else.
Lately, my theory is that worrying is merely unsettled thoughts of the future...but if we don't know the future until it gets here -then its the past and it wasn't that bad.
