Oh my gosh... I'm so sorry you are feeling this way... it's exactly how I'm feeling!! I couldn't believe it when I read your title!
I've been feeling my T. wants me to go away as I'm not interesting enough and disappoint him.
Do you have support at home, with family or friends? I find therapy extremely hard without any other support except for my T. I hope you have someone you can lean on for support-- and coming here is good. By posting you can find others that may feel similiar, --just not feeling all alone helps sometimes. I'm here with you and listening. I'm quite familiar with paranoid thoughts!
I'm sure you don't suck and there are many good things about you! t/c
