Take care of yourself, OK? You've done wonderful things, and anyone with half a working brain cell would realise that you have to put your own health - both mental and physical - first.
Plus you've already done way, way, more than most people ever will - I know it's not a competition, but that's just it. It's not a competition. You do what you can when you can (and when you actually can, rather than over-doing it while claiming you're fine,) and that's what counts.
