Luv's,
I am sure your mother is just being a mother. She will be there for you anytime, as that is what Mom's do for their childern. You are the most important person for her to be near. She'll not want you worrying about her.....
You need to concentrate your efforts on yourself. Do what the Doc's tell you. Let them know when you need them. The Catscan hopefully will tell you what you are up against. It's time to be strong for yourself, and your family. We all hope the out come is a favorable one. But be prepaired if it is not..
Fight the good fight with your health, and the rest will take care of itself. You have many friends who care about you and are saying prayers for your well being. Say some prayers for yourself as well...
Hang in there kid, you still have a ways to go. And your not alone.
Regards, Kirk
