Same story here, but less wealthy. All I can say is forgive and move on. Your dad stuck around, which is something. They delivered the material goods, which is something. And most valuable of all, they provided a valuable counterexample. Stay away from the shrinks. They pour salt into the wounds, prescribe pills, and hardly any of their "research" replicates. Forgiveness is where it's at.

Took maybe a year or two. I see them a couple times a year. Not saying to ignore facts and forget what they are, but to stop holding the grudge and move on.

For the shrinks, I wouldn't call it a "bad" experience, but an unfruitful one. Lots of words, terminology, techniques--just to dig the hole deeper. Better and simpler to just chalk it up to their own limitations as human beings and forgive. You don't get pissed at the dog for not knowing how to use a toilet. As the child, you are made from the same stuff. Without their counterexample, you probably would have settled into the same error.
