Oh fuck you, Grey's Anatomy

This show always makes me cry. I relate way too much to the lead character and I both love and hate it. In the latest episode, Meredith is conflicted about what to do in the following situation:

Her drunk alcoholic abandonder of a father is sick and needs a liver transplant. Meredith's sister is not a match, but Meredith is. He was really good to her sister and her sister BEGS her to help. Meredith doesn't know what to do. I haven't reached the end of the episode yet and frankly cannot handle watching it anymore.

I've thought about this in passing but right now I am tense and upset because I am intently thinking about this. What would I do if my sister, brother or step mother called me and said "Pete is sick and we need to see if you're a match for X body part", and I ended up being a match. What would I do? He has a family right now and just because he treated me like shit doesn't mean I should take him away from his other family, right? But why do I care about this dude? And I barely have a relationship with bro, sis, step mother. Mostly because of him, partly because of my need to cut him out of my life. I think I would do the "right" thing and help, but I don't know. That would give him a reason to then contact me and be in my life, which I can't have.

Also, what if he died for whatever reason. Would I go to his funeral? I have no idea. I do not have respects to pay to him. I would love to support the aforementioned family members but do they want/need my support? Do I really want to explain to my brother and sister, who are much younger than me, why I am have not, am not, will not be around? Do I want to have that conversation with them while they are mourning a person much different than the person I know? I hate thinking about these things because I'll never know how I would react unless it actually happens. I hope these things do not happen, but this dumb show keeps bringing up things I don't even need to think about.

Meredith Grey, stop being a prettier, smarter version of me. Twat.
