I felt exactly the same way with my T - used to hurt the most when I opened up about something that was really hard for me to share. It was like I took a huge risk and put myself on the line and opened myself up for his judgement and his response seemed to read like it was no big deal and it didn't matter all that much to him. I'm sure some of the time it was me reading into things or assigning way too much importance to something that truly wasn't...but even during those times, it hurt like hell and I had a hard time opening up again afterwards.
