That day again

Hi to everyone.
I know this is out there and unsure of whether anyone feels like this. I have a birthday coming up and I don't want to be here for it. I hate the day, it reminds me every year of how few people on my life I am really close to and I always feel happy when it is over every year. I have tons of acquaintances and online friends and some of them are really great people. But I don't have many really good friends (but the ones I have I treasure) and no real 'best' friend.
My point is my birthday comes around and hardly anyone acknowledges it unless it is on Facebook or something like that and I am not putting it on there so that people acknowledge it out of obligation. Last year in my workplace it was my first birthday there and they usually have cake for birthdays and no one even said happy birthday. They are lovely though and again would have acknowledged it if I said something about it (but I had been asked earlier in the year when it was). I know it is such a small thing and I tell myself it doesn't matter before the day every year but I still feel hurt when that day, one day out of the whole year, is not acknowledged really by anyone.
I am just so tired of being overlooked in general not matter how much I try to assert myself and look after others and put myself out there etc etc etc. I am so tired of being me. Sorry for the whiny negative post but not feeling well and sad feelings are gearing up.
