I was so happy to hear that you are in counseling. I think that you have created some important options for yourself along with how you will present them to your mother. I hope that your visit with your sons in Fla. is fruitful and enjoyable....I am always here at the boards.....Your sharing your situation on the boards is a wonderful support for others who may be in the same type of situation.
Just remember, that while you feel as if you are the only child...your reaching out is creating an extended family to support you in your time of need. God Bless You in all that you are doing.
LOVE & LIGHT
