Not sure if your son can understand the whole picture. It sometimes difficult to understand a whole situation, mainly when a "proffessional" like your ex therapist are painting a different picture to your son.

You know what i'm realizing those days. It's not that I am diagnosed with borderlina personality, but, it's only enough that someone hangs this label on you for they thinking or showing you that the only thing they can expect from you is that you have lost your way of thinking in a rational way, you lie or you are selfish...I have been given those adjectives lately and it's really fustrating. I can't even figure out how you can feel when someone like your son can't trust you.
