I'm glad that your first session was comfortable and you feel good about it.

How long before I saw measurable results and change?? well, I struggle with personality disorder/s and complex-PTSD so there isn't a pill for that, that they know of yet anyway -- except to control the depression and anxiety-- it took at least a year to notice tiny changes and now-- after two years-- the changes are still happening-- it's just VERY slow......

was told I need to change my thinking 180 degrees- it's extremely difficult.

Just remember-- therapy can be hard and it can have ups and downs.

Good luck to you
