Is it okay to be jealous abut this?

Okay, so today, I went to the new amusement park with my best friend. We are the best of friends forever and always. But anyways, back to the question/story. Okay, so there was this game in which you could win an i Pod touch. Well, she won it. I was really happy for her at first, but she kept talking abut it and wouldn't shut up about it. She wasn't bragging, but just talking. I got really jealous and kind of mad. I mean, we bought her a ticket to the bark, lunch, and gave her like 20 dollars. I felt like I deserved the i Pod, for we gave her everything and she already had an i Pod, but I never said anything. Now we're home, and I'm really mad. I mean, she has everything. she's had like 5 phones in the past year, she got an i Pod just at random, and she gets to shop at all these expensive stores. So, should I be jealous? Do you think I deserve the i Pod? I know I seem bratty and stuck up, but I'm just upset. What do you think? Please reply!
