Well, it sounds like that was a poor show from your parents, but you may have to forgive them and move on.
Me, I'm at an age where I hate birthdays. I have to tell my sister, "I DON'T want a birthday, don't organize a party, that would pi$$ me off, I don't want to be reminded of how old I am, I don't want people fussing and giving me presents, I just want to be with my family and watch Netflix..."
But at age 17, you still should be having good birthdays.
If I were you, I would take a look at your life as a whole right now. Why did your parents drop the ball this time? Are they busy? Preoccupied? Worried? Is there something going on? I don't imagine that your family and relatives just decided that they don't give a damn about you, there would have to be a reason for something like that.
Whatever the truth is, be strong, and be a good person, because at the end of the day that's what counts.
This may be your chance to show that you are above that sort of thing... that in spite of it all, you are not thinking "how can you help me", you are thinking "how can I help you?". This is a chance for you to do that, and be awesome.
