Do I see what you see (revised)

Recently, a family member of mine called me selfish, inconsiderate, brat, and undependable. Now, I admit that I probably have been and can be all of these things at times, after all I have a sin nature. However, in order to help out this family member, I worked an eight hour day (missed my first day in my "office"), drove three hours, slept four hours then drove another three hours with her offspring so I could take care of the offspring for her. Now, I'm trying really hard not to sound like I'm complaining cause I don't want to complain. I just don't understand. I know I should not care what she says or let it affect me. On one hand people tell me that I am kind and loving. But then she tells me that I am not kind or considerate but that I let everyone down because I refuse to help them out. And they wonder why I question myself. Well, here's why! The person who should know me best says these things about me. Its no wonder I'm confused and hard on myself. Don't misunderstand this to be putting her down, that is not my intention. She had every right to call me those things because she believes them to be true because I chose a commitment over her need. So, my thought is this: do I believe the person who tells me I have a good heart and care about people or do I believe a family member who tells me I have my priorities messed up and I am selfish? For those of you who know me, please clue me in.
