No one said happy birthday to me on facebook?

[E.H]

So it's my birthday today and it doesn't really feel like it since I celebrated it mostly on the weekend. People said happy birthday to me in person already and most of my close friends said it through texts too today and I appreciate that, but I see some of my other friends that are online on facebook, but not a single person greeted me on my timeline. I'm trying not to let it get to me, but it just does and I feel like a loser. -.- I know the day isn't over yet, but I feel like no one cares about me. :/ Since none of my friends aren't replying to me and I'm not talking to anyone right now, it makes me feel like a loner. I know that my family really does love me and my friends love and care for me too, but there's just a small part of me that's making me feel like my friends don't care/love even though I see that they do. I don't know what's with me! I think I might be bipolar or it's just my mood swings. Lol. Time of the month..
and it would say or notify people that it's birthday...
