Nancy, it is okay, sometimes we just need to get things off of our chests so that we can feel better. What a better place to do it then here a place where people will understand what you are going through. Let me tell you that you have every right to feel stressed out and pushed to your limits. You have so much that you are dealing with and are responsible for. Add in this stressful surgery you are about to undertake and you get too much at one time. My heart goes out to you as you certainly need a timeout. You need some you time right now take hold of your sanity. What may be left of it at this point in your life. But rest assured you are a mighty woman and let that be your rock in times of need. Not many people would have been able to do all that you are doing at this time. You will be in my prayers for peace, strength, courage, patience and healing. I am praying that your surgery is uneventful and that your recovery is smooth. Blessings to you.
