RANT...My sister in law is getting on my nerves...

I swear I never get to just relax before going into work. My sister in law always “needs” me to do some kind of bullshit before I go in. She always “needs” me to go somewhere w her or help her w something. I’m so sick of it. She’s 32 & it’s like she can’t do shit on her own.. & on top of all that I’m always taking care of her kid. Like wtf...
