i agree with those.

the next thing you need to do right now is find a diff pdoc and get a seperate therapist. although have them talk/keep in contact if possible.

find some small thread of what your definition of hope is - somewhere. and build from there. somewhere theres a peice you cant find that may help you off this. whether its in volunteering or the like. but i think you need a different physician/pdoc i mean and a diff therapist since they are the same person right now. thats the first thing id do. find a support group.
