Family

Last summer my sister had said some things that my mother had said about me and I had confronted my mom when she visted me and she never denied saying the things. I just can't seem to let it go. I had a fall out with the family a couple years after high school, stayed away for about three years and my sister found me and got me back together with the family, but ever since I just feel my mom hasn't been the same with me, she could of cared less if I went on with my life without them, but I try to make the best of it when I have to visit.
I have not spoken to my mom since her birthday, June 10th, has she called me? or send me an email NO, why do I have to be the one to call? I know she is traveling in the motorhome, when we're on the phone, it just feels awkward, I'm on pins and needles being careful I don't say something that she may take offensive.
I just want to be accepted. I'm adoptive and I know these insecurites are normal in my situation. I just want to live my life and not worry what others think of me.
Till again
