<human>: Can you give me a shortened version of the text?

Throwaway because my friends are really active on reddit and may know my username. 

This past year I started University, and throughout the year I made sure to make sure my close friends' birthdays were celebrated properly. I tried to make them all feel important and special, planned group dinners, threw surprise parties, the works. I'm talking legit shit here.

Fast forward to the spring, and my birthday sucked. They kind of threw together a half assed "surprise" party (which they told me about beforehand) which essentially involved them sitting around drinking shitty beer (I don't really drink). I didn't really think too much about it at the time, I was busy with exams and other work. But now school is around the corner, and my friends are trying to start discussions on how we'll celebrate September birthdays. This is kind of putting the shittiness of last year into perspective and I'm pretty pissed.

But at the same time, am I being petty? Should I bring up these concerns even though this was months ago? Or am I right to be upset and should just ignore these birthdays? I've never been in this situation before and just don't know what to do.
<bot>: my friends didn't celebrate my birthday and made me feel like shit and I don't know how I should be feeling/acting.
