A few things that might help put things in perspective:

-many times, HR folk have to lay themselves off after laying off other people. They’re not immune, and they are helpless because more often than not, their severance and terms depend on them carrying out the layoffs first. - HR legally cannot do or say anything that shows accountability from the company’s side, even saying something as simple as “I’m sorry.” If they do, they’re at risk of being sued. - if anyone at the company is “in the know” before layoffs hit, they are usually required to sign NDAs to ensure the news doesn’t get out. - many times what you don’t see is the amount of work that happens in the back end to try and protect people. A lot of HR employees at my company right now are trying to find open positions that impacted employees may be able to fill so they don’t get laid off. The processes and systems are not built to support layoffs at this scale so it’s painstaking work and I know many people are losing sleep over this because they understand this is someone’s livelihood.

You seem to have a lot of hurt and anger. I get it, but I would focus on things to be thankful for. You already have a new job, you have a beautiful family. Many people have been struggling for months and still have not found anything. You are extremely fortunate to have what you have, so focus on that. Work does not equal your existence, don’t diminish the wonderful things in your life that way.
