Am I Wrong?

I just went off on my mom & I’m feeling bad. I will do anything my mom asks me to do; however there is one thing I don’t necessarily like doing. She asks me all the time to massage her hand. I think I don’t like it because sometimes it hurts my hand. At one point she was only asking me, but two of my siblings live with us also, so I told her a few months I felt a type of way because she was only asking me.

To make a long story short, we all agreed on making a schedule where my siblings & I would rotate & still that’s not the case. My mom has still asked me the most, sometimes my brother & no more than 3 times with my sister. Please tell me the truth, do you think it’s wrong of me to get upset & go off on her? Lol
