When it comes to my birthday, I always feel sad when the people I remember birthdays of, don't remember mine.
 I have a Facebook but I have turned off the birthday reminder so only people who really care and think of me will wish me a happy birthday. However, today when my brother's wrote on my wall, no one has done the same. 

 I feel that at my age, I shouldn't be caring about this. I shouldn't be sad. However, I am still someone who cares what others think and desires a lot to be liked by others. I feel this has a lot to do with the sadness I feel when my friends forget my birthday. They're probably busy or distracted by other things. But I can't shift this sadness. 

My brother's only wrote on my wall because I posted a picture of a present I got today, which I guess reminded them. I believe if I didn't do that, I would of heard nothing from them. Which makes me sad because I always remember theirs. 

Am I wrong for feeling this sadness?
<bot>: friends don't wish me a happy birthday in either text or Facebook and brothers don't remember my birthday. I feel sad and forgotten. Am I wrong for feeling like this?
