For me it's similar to what Skies said - I have generally seen myself as a mess and not a normal person. My T is always telling me I AM a normal person and "normalising" a lot of what I say.
On the other hand, I believed that everything in my childhood/my past was normal and I was having these problems for no reason or because I'm somehow defective. My T is clear that things that happened were not normal, and were difficult/messy for me.
