Is it rude that nobody gives a damn about my birthday?

So today is my actual birthday and none of my coworkers or children said happy birthday. Only two did. Like seriously? It’s my birthday and should be thinking about me and this day is all about me but I didn’t wanna sounds selfish and egotistical.

I am 24 years led and I an young!

My parents said happy birthday, my siblings but nobody said it to me at work. I have a coworker that has the same birthday and they said it to her. Why not me? I was ignored.
