I know what I would do in your situation, Blueberry, but I'm not a particularly forgiving or selfless person when it comes to this kind of a thing. I am completely estranged my siblings as it is so I'm more than used to some pretty harsh boundaries. My parents are a trickier matter because they have provided emotional and, at least through college, financial support. It's just that their support has been very flawed and inconsistent. Plus, my mother is wackadoo, so I anticipate that dealing with her will be difficult. She has zero financial sense and is extremely private (to the point of paranoia) about medical issues, so there's a double whammy right there. Frankly, I'm more concerned about the fact that I'll likely have to deal with my siblings again, something I really don't want to do.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
