This is to the woman who is struggling with her husband's cancer.  First of all, you are to be commended for being a faithful wife and honoring your vows, "Through sickness and in health".  Nobody understands the impact of those vows when they are saying them. You are grieving the loss of the man that you married. For many people this is harder than the actual death Itself.  It happens all the time with couples who are dealing with dementia and other serious illnesses.  Brain cancer is very similar.  It changes the behavior and personality of the person.  It is the long goodbye. The only way to get through this is to allow yourself to grieve.  Give yourself time to feel sad and mad so that you can come to acceptance.   In addition, you're dealing with something that is called "caregiver's fatigue".   This is when a person starts to feel negative feelings toward their loved one because of the difficulty of taking care of them.  You need to make time for yourself and get help for you.
