Do your ever feel like you're not valued as much as you value other people?

I've heard someone say before that you always know your true friends when it comes around to your birthday. Well, my birthday passed a week ago. And I only had two people tell me 'Happy Birthday' who's outside of my family. I know big deal right? But my point is this, I have more than two people I talk to and I remembered all of their birthdays. Every single one ! And they remember other peoples' birthdays. 
~So, 2-5 days after my birthday they start telling me 'Happy Birthday' (or not at all) and this was after I changed everything stating that it was my birthday. One of these people was texting me on my birthday and it didn't even dawn on them and I reminded them a day before. Just thought I should throw this in here, whenever it's their birthday they get mad when I don't remember it or if I didn't wish them 'Happy Birthday'.
~I'm sure this sounds like a pointless rant... It kinda is, but I just wanted to express how I realized some things in the past week about how people will treat you. It kind of sounds like I need to reevaluate my associates huh? Lol. Thank you for reading. 😆
