How are you this morning @Catmaiden ?
It is sad. But it will pass. It will. You have spent 40 years working hard to support your DH and DS...it is going to feel like a massive hole in your life because your life has revolved around them for so long. You have probably forgotten what you enjoy and what you need.
I really related to your ‘listening, soothing, helping out’ comment because that’s me too. Listening patiently to how their day has been, the latest ‘issue’ they have faced, doing small things to make their day easier... It is exhausting. Eventually you will have so much more energy for things you want to do.
This week is going to be tough for you with the move and unpacking but I don’t see how you could have done any more. Use this time to rest as much as you can and do things you enjoy...walking, reading, whatever.
Are you taking any animals with you?
