I can't overemphasize enough just how important it is to take the best care of yourself possible throughout all of this. Go to the gym if you can, or get any form of regular exercise that you can. Take some doxylamine about 30 minutes before bedtime...you can get it OTC at Wal-Mart. it's hard to accept that you have no control at all over another, especially in these situations, but you do have control over you. So exercise what control you do have. Take care of you, first and foremost...now that you're in this situation. I'm very sorry that you're having to deal with this painful stuff.
