For context I (F17) and my sister (f16) didn't have a good childhood and because of that in the last year she's went to a mental hospital twice and had a mental breakdown at school to the point that she pretty much instantly dropped out. She is now "working" on getting her GED and by that I mean she sits down with our dad for an hour or two a day looking at the book. Now she does choirs around the house and gets paid for it (I didn't when I did) and they said I could too if I helped out around the house the thing is I go to school still and I have an after school job that I work at 4 days a week. The remaining days I'm usually exhausted and I go to therapy and hangout with my bf. Now here is where I might be the ah. Yesterday my sister said she'd come with me to visit our father (my parents are separated and we usually go to see him on the weekends) but last minute she bailed saying she just didn't feel like it. Shes been having excuses to not come to anything with me since she dropped out a couple months ago, and I finally had enough. I told her "you never 'feel like it'" to which she replied "I work hard around the house" "you do? I go to school for 8 hours then usually have a 4-5 hour shift after, and you think you work hard? You get to live the easy life." I kinda feel like I was too harsh on her so am I the asshole?
