what a bad ending to a fine day

One of the worst things happened today. I lost my freakin atm card. I have no idea what happebed to it. I was in my bank's parking lot and I was about to make a freakin deposit and there I saw it is missing. I was so frustrated I had no idea what to do. I called my dad and he told me to just call the bank and block the card, which I did, but I am still upset. How could have I done this? I was always so careful. I wanted to make the freakin' deposit and then oops the card goes missing.
