Some of them didn't even wish me a Happy birthday
and I got no cards, nothing.
These are people I consider myself close to.
I must just be like a massive asshole or something

In your case, dis your friends know it was your birthday? If so, it's time to find a better class of friends. If they didn't know, give them a break. They might feel bad about missing the opportunity to give you well wishes.
It may be late, but Happy Birthday! May this year be filled with joy and happiness!
