I recognise much of what you are saying Tanglerose - the adrenalin you have been running on over the months and years of being strong for you family, has run out and now you need time and understanding to recharge your batteries. I felt very much like you for a few months after retiring and also after DH's periods of illness - once the strain is off a person is much more likely to go to pieces. Time of year doesn't help either- dark, cold gloomy. Take some deep breaths, do not set yourself any targets- having all the time in the world is not the universal panacea many people think - you can feel aimless, rootless even useless, but once you feel ready, I would suggest some fresh air - countryside or seaside, some visits to nice places you have always wanted to see, a bit of pampering if you enjoy that and then once the Spring comes - look at how you want to spend your time - who needs you and what you will enjoy doing. You are not unique in feeling like this- my SisIL retired from being a GP 9 months ago and despite knowing my own experience of how you often feel worse before you feel better, went through a period of real depression. Don't force yourself and don't commit to too much, but you will find activities and people who will help to give a new form to your days. 2 1/2 years down the line I feel I am in a good place now, but it took time.
