I lost everyone that used to feed me sanity!!! I had a similar but not so drastic weekend as yours.
H has been getting chest pains and anxiety attacks and it is all self-developed. He creates thoughts (worries/fears) in his head - and develops them into what-if truths.... This all turns him into an anxious mess which is then of course overflowed onto the kids.
I'm finding my strength slipping away sometimes in handling all this. It very much like I have 3 kids and the kid I married is my most demanding one.
