Is it normal to be disgruntled?

Is it normal to be disgruntled after a layoff?

I got laid off my IT role for a biggish MSP firm, they just called some people to say they had difficult measures to take, I was one of those people..

So a month and so later, I'm still searching and I just feel bitter and jaded, I'm not getting calls back.

Is it perfectly normal for me to feel this way about companies? I'm still confident I can try to get back into it from this setback but I just feel these firms no matter what industry they are, are utterly void of any camaderie.

Am I going insane?

(TLDR - Bitter Bri'ish guy who's just asking if being infuriated with this isn't like a mental disease)
