I wouldn't be too hard on yourself Cas about being in the same job, house etc, you have had a lot to deal with such as your surgery and yes kids and school and their social/sporting activities do make it that bit harder.
I think even if you just start to do some things that you want that don't require you to move or anything drastic like that, it will feel like you are mixing things up a bit.
It would be lovely to meet, so please do let me know when you are next here.
