It is very hard. i'm still struggling with just such a change, although mine wasn't so i'd have someone better. My old one just flaked out. i'm sorry you're struggling so much but i hope your new T works out really well for you. i think i wasted a lot a lot of time with the wrong T even though she helped with some things and was really nice.
But, however it turns out, it's hard RIGHT NOW and i'm sorry you're going through that. i hope you feel better really really soon.
