I agree with you 100%. I try hard to learn how to slow down. We preach it to others, but following our own advice is the hardest part.
I'm a caregiver to my husband, and finding that quiet moment for reflection is often impossible. The guilt of taking time for yourself can be huge when someone else depends on you so much.
For me, two things have really helped. First, I started setting a five-minute timer every day, usually right after he finishes lunch and takes his short nap. I can just sit with a cup of tea and do absolutely nothing. No phone, no checking on him. Just staring out the window. It doesn't sound like much, but it breaks up the day's pressure.
Another big thing is learning to accept help, which is something I struggled with for years. It could be letting a friend run an errand or just using useful technology to make my life easier. We got one of those smart TV setups, it is specifically called "the JubileeTV box". He loves watching his shows, but due to his bad memory, he often forgets how to use the remote properly. This box has a simple remote with big buttons, which he handles well. It has sensors that detect movement, and a camera, which gives me a piece of mind when I have to go out.
If he needs something, he just presses one button and starts a video call with me directly on the TV. Also, I can set him reminders for his meds and send him pictures and videos, so he feels connected when I am not there.
This worked for us, but whatever buys you a moment of peace, embrace it. Don't feel guilty because it is not easy. We deserve those pauses, especially when we're giving so much of ourselves.
