Confused and Lonely

I don't know where to begin. I have a parent that was so healthy and one day it was over. Today I see a woman that I look up to and see that isn't the same and it hurts, because there isn't anything I can do. I see myself running away from her and it kills me because I love her so much. Why does a person have to become so ill as that? I see myself just like her, loving, caring always wanting to help someone, and never looking at myself. I'm so confused why would a beautiful woman that was always loving and would do anything for anyone in need have mental health issues in her life? I look up to her. Now, when I do choose to visit her, I wish I had a magic wand and made her well again. But I know I can't and it is taking so much energy away from me. I'm confused and so lonley without her....
