Yes. I found it much easier to deal with things when DH was here.
Even now, I sometimes find myself in a position that I only rush to get things done when there's a imminent deadline. Maybe that's just me, though.
At one point, I was working full-time and caring for both my mum and my husband. I thought that I'd be on top of everything once I was retired, but I'm not. However, I have to admit that that might be a me problem.
Breaking things down does help a bit. Sometimes it's a case of starting on something and then just doing what I can. Maybe not a good example, but the latter is what I'm doing with the garden at the moment - have cut the boundary hedges and now I'm just strimming what I can. Yes, the garden is that bad.
The garden's easier to deal with because at least with that I can see the difference I've made.
I recall going through a manic phase in the first year (maybe two) where I ordered literally hundreds of bulbs without realising how many I'd ordered and then had to plant them all. (Those in the front largely fed the local squirrel population, I think.)
I've had various plumbing problems with the house and everything is just in a guddle. I need to sort out and throw out, but I had various health issues to deal with and then an unexpected legal matter hit me... I find myself only being able t do one thing at a time.
I'm still finding it difficult to deal with more than one thing at a time. I think that that might be because my husband really was my only family once my parents were gone. I do have cousins, but it's not the same.
I'm feeling guilty because I feel I spend time at the gym when I should be doing other things, but it helps me to keep my sanity. (I joined two years after DH died.) If I sign up for a class, then it means that I have to leave the house, because the instructors lose money for no shows.
When I'm in the class, it's easier just to focus on that. Same with going to back to an instrument lesson once a year after a 20 yr break. I have to do my half an hour practice a night and then I'm only focussing on the music.
Think I need to try the same focus on sorting out the house.
It's better than it was, @Roseshavethorns . I've been told I probably have ADSD and ADHD so maybe that has something to do with it all in my case. (It runs in the family, but my only diagnosis is OCD.)
Sorry. That's probably not very helpful.
