sh- I hope things are getting better for you since your "sighting". Don't worry about why you got the credit card or the bag or whatever. I know you have heard this a thousand times before, but do your best to put all of it out of your mind an keep moving on. We would love to understand all of the "whys"...why did this happen?...why do they treat us this way?...why they can't get their head out of their a$$?...etc.,etc.,etc...but we may never know and we have to accept that for what it is.
This little run in has temporarily thrown you off your path...pick yourself up and dust yourself off and keep on going. You are going to be fine...and you are working your way to a much better place.
