for me, when i have strong emotion(anger, envy, sadness, fear, ...) toward therapist, talking about it helps a lot, but it doesn't fix it. Time makes it better.
So the talk is important, but it takes me time to process what we talked about and to feel what I need to feel. I fiigured out i can't stop a feeling, more i try, worse it gets...
Some other time, the strong emotion is just replace with an other strong one, so i would end up in a no better place, just a different one that suck as much....
