Ok. But don't totally diss the idea that the anxiety and unhappiness might be coming from the separation... maybe some anger about it, maybe about it not happening sooner so you could have had a happy childhood?
Can you begin to develop a new relationship with them now, as an adult? Are you relying upon anything from them still? That would mean you do have to have a relationship still...
Do you realize it is very common to suppressing painful emotions and to try and dust them off as non existent? A divorce affect everyone... how did you find out? Who told you? How did you feel about it when you heard? Did you agree with what the parent who told you said? These are rhetorical questions... things I guess you talked through?
The reason I am sticking with the divorce issue is because, imo, if it was truly settled within you, it would not have been in your first post in the depresson forum.

I believe we know, inside, what is troubling us, even if we don't realize it consciously.
I need to sleep now...but will look for any response later on, ok? TTYL TC!
