Ohhh Mimi, I am so sorry. You must be worn to a frazzle.
It's time to start recharging your batteries. Take a little time here an there for you. I am not talking about hours and hours. I use to go for walks around our property. I helped calm me down and cleared my head. Take bubble baths or read magazines. Just anything that you like, to take your mind off of your reality for brief periods of time. For your own good and your husbands, you need to take care of yourself too. If you get sick, you will be no help to him.
Did the doctor ask you how you were going to manage his care when he came home? Maybe you need to call him and have a long chat with him. Ask him the prognosis. If it is less than 6 months or maybe a year, hospice can be called in. I called them in for my husband and most recently for my brother.........they are a wonderful organization.
Take care..........thoughts and prayers.........
