OP sounds very bitter and - frankly - melodramatic. Getting laid off is terrible, but this person makes it sounds like they'll never heal/never be the same/all companies suck/etc. when none of those things are true. There is an implied business relationship with an employer that can end anytime, and that's expected because it's a two-way street.
I agree with the top commenter - seanc - when he says:
> Carrying around bitterness and cynicism is just bad for you. Pride in good work and pleasure in having an impact on customers and coworkers is good for you. Sometimes that means making dumb business decisions like sacrificing an evening to a company that doesn't care, but IMO that sort of thing is worth it now and then.
Finally, income diversification pays huge dividends. I had a startup job where suddenly I found myself with a $65k/year pay cut one week. I had side work from folks who were asking me for more anyways so I quit that same week on Friday. Now I employ 10 people and pull in nearly a million a year. Really makes the emotional part of having lost income that week completely meaningless in the long run.
