Don't worry about it, I did the same thing at a stoplight one time and unfortunately a cop was right there. I had a totally clean record and I explained the situation and thankfully he understood and let me go (not before a stern warning lol). I occasionally suffer from really intense anxiety too, I know how you feel and I know how situations like this can scramble your mind. And I know how we're all struggling to save money in this insane economy and how even one ticket can be a real burden on a lot of people. But I promise you'll be ok here!
