From the facts which you present, it sounds like family counseling should be your first choice and not divorce mediation. Severe sickness or disability of one spouse places a tremendous emotional and physical burden on the healthy spouse, and it is not unusual for you to react in the way you are. I strongly suggest you seek out an experienced family counselor to help both of you. Get home care assistance to take part of the burden off of you and to provide you with some free time to go out and to enjoy yourself with your friends and family.
If, after family counseling, you still believe that divorce is the only solution, I would be happy to discuss the matter with you at greater length.
