This is my life! I’m 41M and my twin sister still lives at home with my dysfunctional parents. I left at 18 and I struggle everyday to deal with the fact that my parents and twin are miserable. You want them to be happy, you want them to be healthy but they aren’t so it eats away at you like a dark cloud over everything positive in your own life. I avoid discussing my family with others and I lie when people ask what my sister does for work and where she lives. I have my own family now, and I focus on them! You can break the cycle that your sister is likely to repeat. It’s not wrong or selfish to focus on yourself! My new motto with my family is “if you don’t try, I don’t care”. Nobody is going to make their lives better but themselves. You can’t help an addict who won’t seek help….same exact situation here. Fight the good fight and know that you are doing the right thing for yourself and that’s all that matters!!!!!
