Well done for going to Toastmasters, must be such a confidence boost to stand up in front of people and speak. From my experience of being too busy, it's a double edged sword - the key I think is being busy at the right things, being busy at the things you WANT to be busy at rather than stuff you feel encumbered to do. There's a good book The Power of No by James Altuchur that talks about precisely that - and for what it's worth your health and you family sound about right to me! James does waffle into some higher energy stuff which you can ignore (or not!) but identifying the stuff you want to be busy with is important.
There's a George Bernard Shaw quotation which I find excellent:
This is the true joy
in life—that being used for a purpose recognized by yourself as a mighty one.
That being a force of nature, instead of a feverish, selfish little clod of
ailments and grievances complaining that the world will not devote itself to
making you happy. I am of the opinion that my life belongs to the whole
community and as long as I live it is my privilege to do for it whatever I can.
I want to be thoroughly used up when I die. For the harder I work the more I
live. I rejoice in life for its own sake. Life is no brief candle to me. It’s a
sort of splendid torch which I’ve got to hold up for the moment and I want to
make it burn as brightly as possible before handing it on to future
generations.
