I think working hard and being warm/supportive are not mutually exclusive traits among therapists. Mine is happy to get into the deep, difficult stuff, but she is careful to do it in a way that allows me to function in my life outside therapy. She's there for me between sessions when I need her, and she listens to my feedback about what I need from her. It's hard to think she doesn't truly care about me, although sometimes I still try my damnedest...

Maybe you can look around and interview a few new therapists to see how you feel with them? In my opinion, therapy should be challenging but not destabilizing. It's the difference between going to the gym and feeling satisfyingly sore afterward and going to the gym and pulling a tendon. A good T can help you strike that balance.
