Sorry, that came across super self-pitying, poor-little-me
Frankly you are perfectly entitled to feel sorry for yourself, but you actually sound really fantastic and I wish I knew you in real,life. Your children are very lucky.
It is shit that you've got the double whammy of shittiness, but look at it this way.....write this year off. Get better. Get stronger. Get through it however you can. Your children are very young, in years to come they probably won't even remember this - but what they will remember is all the fun and adventures that they are going to have with you when you get better. Hold on in there.
