none of us here know the long history of the dynamic between yourself and your father or the family unit dynamic as a whole   we can only go on what has been stated here   with that i’m more curious what your response was because this seems like it could have a moment to non combatively reach a point of understanding or to open a dialogue if he cares enough to acknowledge your struggles and to even offer his own unsolicited and misguided advice then there may be an opportunity to convert the dynamic from a position of misunderstanding and judgement to him understanding you himself and even becoming an ally and partner   adhd is misunderstood even by the people who live it daily recall the work that had to be done by you to fully understand the mechanics of it all no one here magically became adhd knowledge wizards because we suffer from it it took a lot of research observation and discussion to know some parts of the big picture   in a sense writing him off is also writing your own self off
