Well, there is no point in being bitter. It isn't going to make them better parents.
Everyone is screwed up, it usually isn't their fault.
But we just try to do the best we can.
On days we are both sick or when life just beat the crap out of us and we just can't be emotionally available right now. We just do what what can, even though we both know you deserved better.
Sorry kid,
still working on doing better
