You said it, and you hit the nail on the head, to be kinder to oneself, and to take a little bit of demand off the table. Sometimes we are too demanding with ourselves and that makes us unnecessarily stressed. Then we become unhealthy.
Of course it has happened to me, too much responsibility and overloading myself with things. I'm like that, I didn't even realise I was doing it, until the body takes its toll. So I had to give things up and delegate others, learn to delegate, I'm not supergirl.
Now I will tell you that the change of thought helps a lot, I would never do what I did again, like taking even other people's work, a different thought and attitude changes everything.
You must weigh less... I mean in your mind. Free it, for example nature helps.
