My dear friend ~ We haven't talked in awhile, but every time we have I've tried to impart the same thing. You are worthy, you are important and deserving of everything that everyone else has - which is love and caring!
I'm afraid your mother just does NOT appreciate you at ALL. I don't know why. You do everything you can for her, and she still doesn't appreciate it.

It's only natural that this would hurt you especially when you get sick or hurt, she does NOTHING for you and even taunts you on top of it!
I'm afraid your relationship with your mother is toxic -- and the sooner you can get out of that home, the better. It would be great if you could live with friends or other relatives. I know it's expensive to live on your own!
I hope you know that there ARE people here that you CAN trust to talk to! There ARE people here who would NOT let anything go any further. You need not feel that you are totally alone. You do have friends here -- lots of friends, who would certainly be there for you.

Please don't feel alone. We DO care about you, my friend. I know I do. Please take care of yourself. God bless. Hugs, Lee
