Brenda: God bless you, dear. We will certainly be thinking of you and keeping you in our prayers as you begin this journey. I'm thankful that you appear to have a good support system in place with your mother and your sister.
Just remember, you are NOT alone; SO many of us have begun our trek down this dark path; now, we're all holding hands and believing together.
Try to stay strong, don't be afraid to ask questions, and read, read, read!
