Oh, I'm excited for you WePow. Your mentor must be a wonderful person and your T. too.

I'm not sure about the negative talk--
could it be that you are just unsure if you CAN accomplish what you hope to on Tuesday? like the before stage jitters?? or maybe it's that there's a part of you that you've held for so long(even if it's negative) and after Tuesday you're not sure if that part will be necessary anymore....
I wish I could help you more.

anyway-- please know I'm wishing and hoping things go well for you
