LarrysDaughter,
Have a Hug!
You said it all and you also felt a little bit better at the end of your post, in my opinion. Rambling is one of the great things people do here and from what I have read they usually wind up helping themselves and others as well.
We are all pulling for you. We all have an idea of what you are experiencing and don't mind at all if you need or want to lean on us or just listen and offer advice when we can.
I rember my wife going through similar emotions and have no idea of what it is like to be a bystander who is in your position. I hope I never do but, if I am, I'm sure I'll re-read this post and take comfort in the fact that I am not alone.
Your father is very blessed to have you looking out for him. You mother, I am certain, admires her daughters love, caring and strength. You don't have to be her mother but you can be her friend. Tell them both as much as you can that you love them. It's a very simple thing but it will make you and them feel so good and help your process.
Keep the faith, this roller coaster is a beaut!
Take care of yourself too. Get plenty of rest, eat right and exercise when you have time. Take notice of all the simple pleasures that you have in your life. This type of fuel will help you keep your strength and allow you to continue being the loving daughter that you are.
I for one, admire you efforts!
My thoughts and prayers are with you, Larry and your mother.
God Bless.
Mike
