Thanks for all the well wishes. Day 1 and I've taken my dogs for a long walk, taking in a couple of property auctions for free entertainment along the way. Total cost $0 and the feeling is priceless!
Re guilt, that mainly came up for me from my MIL's attitude about it a few months ago when I announced my ER intentions. She's an old school catholic, so after a bit of research it is possible that that ER equated to "sloth" in seven deadly sins parlance in her mind. Fast forward to now and she seems to have come around, calling me up yesterday and congratulating me for "earning" my change of life. She seemed to mean it, so all is good in the family circle!
