I remember once when my Mom, who is a lovely lady, but I lost 60 pounds and she said "you're getting too skinny." I was so distraught that she wasn't happy for me, and supportive, I gained the weight back. Now, that was my response to her words, but still, I felt badly.
Moms, controlling or not, always want their children to be right where they know they should be. Your changes probably scare her because she is afraid of being left behind. I know you know that, but it doesn't make it easier, does it? Your mom will have to come along because your changes are permanent, right? Now you have several people in your life throwing fits, and it must seem like you are the crazy one at times.
It's so hard to stand on your own. No wonder we were meant to be in pairs, our lives are so complicated now.
