trapped in my old mind

This is scary. I understand it is common also. It was a good part of my amorphous fear. I cannot say exactly when it went away. I believe it was when I was first engaged in a subject at school that I had no prior experience in and had to communicate with a learned individual without relying on my memories. It was a profound shift for the better when the feeling abated, and I strongly recommend dealing with this issue quickly as it makes most others easier.
