Am I overreacting/what do I do now?

ok it's my birthday . I turned 19. And so far it hasn't gone well. My thoughts about how a birthday is supposed to be is. Everyone eats AFTER the birthday girl has been served food. And she is sung happy birthday etc. And it's all about her right?? Well as I was getting rdy everyone began eating. I had the perfect outfit and it was perfect with a certain hairdo that I don't know how to make. So I asked my mother to hlp but she left to attend the guests. Plus she invited ppl who I have no idea who they are!....am I overreactoing.?? It's not like I'm ungrateful that they made me a party but...a birthday is a celebration of someones birth...and I don't feel to appreciated or loved...is that wrong .cuz I'm not having a goodtime. What should I do know
