Just thought of another thing my T said - the more we start to trust T, the more difficult it may feel for us. When we don't trust at all, we don't give anything away and it all stays safely tucked up - so no risk there. When we start to trust we let things out and then the stakes become higher in the consequences of that trust being breached - so when it starts to feel more scary can be when we start to take those risks in trusting more. I think this may be connected therefore to vulnerability.
