Wow! One has to think deeply when reading this. Self introspection in silence and solitude at a moment arranged normally by nature is a great thing.
2 burn outs have also put us on the rocks, the last one so bad that I had to have a major operation and you are right, as the flame inside dwindles.

The past year and a half everything changed drastically as we started a new life in a different province and we also scaled down on our daily humdrum, same old, same old existence. Life is to be lived to the full and you simply have to make time for yourself. Our biggest mistake was not to delegate simply because we thought that we were the only ones that could do everything.

Now I have laid the reins down and consult with local charities if they need advice. We still do the odd new project here and there, but the difference is no more at a frenetic pace. No more stresses at night and no more staff hassles.
I saw my mom burnt to a frazzle because she was the sole breadwinner of our small family and by grace she was taken away at the fairly young age of 50.

Why am I sharing this? In the hope that you will take care of yourself as you only have one life. Many love you and that is great, but the flame inside is more important than anything else. Time to find yourself again methinks.
From what I have read you are on the right track.
Blessings to you guys!
