Am I wrong?

Want everyone's opinion. I grew up with my father's family. He died when I was young and they took care of us but to me it was always at a cost. I remember when I was around 12 my aunt told me she wish she hadn't taken us from my mother and the only reason she didn't take us back is because of what people would say. Her kids were older and by the time I was a teenager they were married and had kids. I always had to go help my cousin with her kids on weekends when the Helper left. Even in college. Other times I'd go to my aunt to help out around the house. These people will cuss and make you feel like crap at times and I stick it out. I'm currently 22 and my aunt called one weekend to asked me to to go help my cousin and I told her I couldn't because it was my birthday and I had plans. She went off on me and told me how they helped me and it's my turn to help them and I'm out there looking work instead of being in the house fixing her food and stuff. I didn't really say anything and then she hung up but the next day she sent a message saying how she sees that I'm telling her thanks but I don't need you anymore. ..so I decided I was done after 15 years I felt so trapped by them I wanted to die so I walked away. Just didn't call or go by there. It's been 3 weeks and everyone is calling now and I'm not answering but I know they just want to cuss me out. I want to know...do you guys think i went about it wrong?
