Do what you can, growlithing. Know that, if she does cut you off, you will survive it, as many have before you. It might be difficult, but you will find a way. And that she'll be doing you a favor in the long run.
We're all here for you. Keep in touch. Take good care of yourself, eat right, take walks, whatever is best for you. And remember--you own your life. No one can take that away from you.
