nobody said happy birthday to me today, is this normal between friends?

Heyy, today is my birthday, and I'm not posting this to have you all saying happy birthday to me, but it actually breaks my heart that none of my friends said happy birthday to me. I don't have like 20 friends, but maybe 3 or 4 that I really appreciate and I'd never forget their birthdays. I wanna ask you if you remember your friends' birthdays. Even if you're really bad at remembering dates (not my case, I even know the birthdays of people that don't know me at all, but I understand that not everyone is like that). Is it normal not to say happy birthday to your closest friends? Also, I have just 1 friend that I'm extremely close to, and she posted my birthday on her Instagram, and I'm pretty sure everybody saw her story. Also a few of them follow my mom who of course posted it. Why wouldn't they say happy birthday to me? Is this normal? Do I have friends that bad? Do I deserve them? I have a good relationship with all of them. The worst part is that this is not the first time; it happens every year. But I hoped this year would be different. Also, if you've been in the same situation, it would be nice to know that I'm not the only one. This is why I hate birthdays. It's always so lonely.
