How do I not feel so dependent on T's approval, and so crushed when she doesn't understand me?

The last few sessions, T hasn't been her usual gentle, empathic self, instead she bluntly disapproved of some decisions* I made that I felt were right for me.

That was 8 months ago, and I haven't been able to go back out of fear of feeling stupid and misunderstood again.

*My decisions turned out to be right (at least in my opinion), and I appreciated her different point of view, but I still felt hurt when she didn't understand the emotional struggles and reasons behind my decisions.

I finally made an appointment for next week, but I'm scared to tell her anything, what if she disapproves of my ideas again?
