I am so sorry to hear this news, but I admire you for caring so deeply for your wife.
Please make sure all of your beneficiary information on investments, life insurance, etc. is up to date. If you own any of these instruments in your name only, be sure to put them in your wife's name also. My dad left 11 life insurance policies, some of which showed he was the sole owner of the policy. That caused probate to be stretched out for two and a half years.
If you don't feel up to taking care of such things, please hire someone who can walk you through the process, perhaps a trusted attorney or your executor.
Write love letters to people you will leave behind, kids, grandkids, neices, nephews, etc. May God richly bless the time you have left with your wife.
