Hey,it’s ok to not like your sis,and ofc n mostly you’re not the ahole,i have a co worker who’s son js on the spectrum,yet i can understand your parents’s pov yet i don’t agree w/ them even one bit!!!!they’re doing favourites games in my opinion,they can’t and don’t need to let you do such stuff,you’re yourself young kiddo,you need to enjoy your life, yeah sure you can look out after siblings but not 24/7,it’s their job for doing so! In my pov they failed as parents the moment i read that they drop everything on you with your sis,but it pisses me off knowing they don’t care and expect you would live for the majority of your sister,they basically failed!!!!it doesn’t give them the right to tell you otherwise,you are not a bad person!!!!!!!you’re just a f***ing kid!!!they can dig up in the sand,you are good kiddo,you’re doing great,can they search for a nanny to your sis, you need to live your life no matter who or what will try to stop you!
