Fuck this shit in Hummm

My sister is just a shit parent and I can’t bring myself to say it to her face. She is a fucking shit of a mother. Our mom takes care of her children and she .... why can’t she put them first? Why can’t she realize that she is hurting them by being that way? I know she loves them, and somehow she has made this excuse in her mind about not being there for them. I saw them just minutes after being born, and I can’t do shit because I am not their parent, I am not even in the fucking state where they live and it hurts like fuck to not be able to do something for them. She has them right next to her and she is full of shit, she washed her hands and leaves them like packages with my mom. It hurts to see my mom fading away because she can’t keep up, she isn’t as strong as she was, it hurts to see those kids grow with a woman that barely pays attention to them when they really need it, it hurts that my mom doesn’t allow me to go back home and try and be of help to them. I am angry at my siblings, I am angry at myself, and I am hurt. Everytime time I think of finally giving up on life, they are the first thing that pop up when I am crying as I feel tempted to make that day my last day. What went wrong with our family? We may not have been perfect, but we were happy.... and now we are drifting in this world. I want those kids to have the happiness I had when we were children, to have a mother like our own who would make us smile and feel loved despite the scolding, we knew we were loved, we know we are loved...... why can’t my sister do the same for her children?
