PP--I skipped over everyone else's responses so if I end up repeating something that has already been said, I'm sorry...

It is obvious that you have a huge burden to bear, day in and day out.  Although you do so willingly (or so it seems) you are only human to want to receive a little gratitude for your daily sacrifices.  I know a number of others in situations not too unlike yours who often feel the same way.  One person once told me that the person her husband had become was in fact not the person he was before the illness because his cir****tances had so drastically changed every phase of his life and he was coping in the only way he knew--anger.  She found some degree of comfort knowing his anger was really about his situation not about her.  He used the only bit of control he had left in his life--badgering his wife and getting an emotional response from her.  Perhaps if you see it this way, you might be slightly less angry and realize he has lost all other forms of independence.  How sad that is for both of you.  Imagine him knowing he can never escape his torment (a damaged body) but you can get up and walk out the door.  Imagine how we'd feel if we were in the same place.

Can you arrange for respite care?  I think it would do you good to have some time each week in order to take care of you.  Also have you considerd getting some help for the lawn care and other big jobs? 

I hope you get some rest.
Hugs,
