Your story is so sad. I wish there was a way I could make you feel better. There's nothing worse than inconsiderate people. I have recently had my boyfriend's friends over at our place - most of them I really DO NOT enjoy. I started to get claustrophobic and hurt by how reckless they were getting in our flat as they got more and more drunk. I eventually had to go to our bedroom, take a sleeping tablet and get out of the situation. I also heard them saying nasty things about me.

But I just need to find peace in the fact that these are not people I choose to have in my life. Their opinions are NOT allowed to matter.

I hope you can chat to your daughter in-law and understand why things materialised the way they did. Be honest about how she hurt your feelings.
And as has already been mentioned; don't be anxious about possibly being admitted - it is a solace and you can be away from everything.
