Funny thing is that i had a negative experience helping someone who was laid off. I reached out, offered help, provided excellent reference for them, covid hit and hiring froze for that particular company, followed up a few times, ghosted, never talked again. It's you last phrase, that's the way the world and people works. It's people with their own troubles, insecurities and character. The most important bit is be yourself. If you are "built" to think and help others, keep doing it. If not, whatever.
