Oh sweetie, as soon as I saw you had a thread, I jumped right in. It is good to see you, though of course sorry to hear what is going on in your world.
It is hard (especially for givers, I think) to recognize and stand firm regarding their own needs. But you really DO need what you need. A break. Not optional. It's yours. Take it. (That's an order! )

Try to avoid feeling overly-responsible. (Again, hard for givers!) Others need to step to the plate. Show them the plate, and step aside. Because you know how it is -- others are perfectly happy to keep letting someone else do it(!)

Long/short -- YOUR TURN. Do the constructive and positive things you need to do for yourself. The world will not end. In fact, it's a step in the direction it'd be good to see things go, yes? That the load be more evenly distributed? That's a longer term goal of course. I'm just pointing it out so that you can see how much in line with that this small step of self-care IS with that. It might make it easier to do when you look at it in that light. It's a good thing. And not just for this moment.

Try that perspective on. You like?
