I went through a very similiar change some years ago when I divorced my wife of 26 years. I left her the house and everything and I moved out to a tiny one bedroom apartment. The change was intense and utterly exhausting. The one piece of practical advice I have is this: be a VERY good friend to yourself. Don't overdo anything. Set clear but small goals each and every day. You must sit down and read, if only for a little, each day. It will get a lot better. CHEERS and good luck. Bob
