My T. just commented recently about how much I'm processing in between sessions. She said I'm doing a good job of relating things - certain feelings to the past or my mom. I wouldn't have had these revelations if I had not been thinking about therapy. I just think that's a part of it.....especially if you're motivated to get better. Maybe we will think about it less as we get through our "stuff".
The times I don't like thinking about it so much is when I'm sad around my family due to my thoughts/feelings. As long as it's "just" thinking and my mood is content or better, I can handle it.
