Been reading through your thread tonight and truly hope the day hasn't been traumatic. It's a big, big change when our loved ones go into care. I never thought I'd see the day when it happened to my hubby, and I have missed him so much.
Having busy plans helps stop the thinking process, but the nights are hard for a time. Being able to choose what to do and how to do it was strange for me. I'm more used to it now as I have lived alone before, but that was a long time ago. I don't think I'll ever get used to not having someone here any more, but we learn new habits all the time. I can only advise you as I was advised yesterday to pick up whatever threads of your own life you can, after you've rested a while, and taken stock. Take up a hobby, get out and meet people when you're not visiting, or otherwise busy. Don't allow yourself to stagnate and not go out.
I truly wish you well, Dumpy Girl, and hope things settle down soon for you and your loved one. There's always a listening ear on here when you need one, xxxx
