I Get Jealous Easily

So i am very jealous at my best friend right now , but rather than pure greed , it's more of a dissapointment of myself . I'm so mad at myself because i couldn't be as good as my bestie at school . I really wanted to register to this elite school , but it has some requirements that i'm not sure i could pass , and since i doubt myself i decided to not register myself . But today , my bestie just told me that he register himself to that school , i'm so happy for him ! but i'm also dissapointed at me because it's a change of us to meet if only i register . We haven't meet each other in 4 years now and i miss him so bad . I just love school and would be happy if i met him , but i guess it'll never happend ever :"(
