Am I the asshole for feeling this way?

I have many friends and I celebrate their birthdays to the fullest. I give them huge baskets of stuff of their liking, spam my story of memories, say happy birthday, and for holidays little gift baggies. But their birthdays are September-May. So this is during the school year yet I don’t think the date matters because we see each other during our summer break. My birthday is in June. What happens on my birthday with my friends is that I receive a text of happy birthday. That’s it. Nothing more, and don’t get me wrong! I appreciate what my friends do and I’m grateful for them! It’s just that I feel unappreciated. Like recently, there’s a new person in our group and it was her birthday. My childhood friends (they’re brothers) don’t really do much (not for me anyways) and I saw on the new friends story how they got her a basket of stuff, did a little cake, and went somewhere. They have only have known her for about 2 months. I don’t want to feel like this way because they are my friends. Am I the asshole for feeling like this way?
