Some lawyers specialize in traffic tickets, believe it or not. Their fee is usually less than the fine, but if it isn't, they typically delay and delay and delay until the police officer forgets about the ticket and just doesn't show up for the hearing. Then the ticket is thrown out.

Unfortunately, this is the best system we have. You can fight for your right to be heard, but the process for that is so long and arduous that it could end up being more painful than sitting in the courtroom. I think @corpsvalues hit upon the best solution.

Sorry to hear about your struggles. I don't have PTSD, but I'm not a big fan of large crowds or courtrooms, either.
