Wow. I know the feeling. The previous repliers had great ideas about writing things down and such. It is possible that when you are finally face to face with the T you unrealizingly feel your issues can suddenly seem to be mundane or petty, which can be due to poor self esteem. I say write your issues down and describe exactly how much they affect you. This can be extremely useful. Your T is getting paid to listen to you so don't hold back!
