My court appointed attorney is awful. He is horribly rude, telling me to "shut up and listen" on our very first phone conversation. He can be rude, fine, I didn't let it bother me. He has also given me wrong information, bullied me, etc.. It is very close to our trial and I'm not sure my chances of obtaining a new lawyer on such sort notice, but I'd like to try. What is the best thing to do and how do I dismiss my current lawyer? Is it advisable for me to represent myself?
