I'm so jealous of my little brother

He's 14 and already had sex with a girl, he's already getting attention from a bunch of girls in his school, I'm 23 and still a 2 dimensional gay sorry this is a throwaway and I don't know what to do so I'm just gonna vent it out in here, I'm just so jealous of him, I'm just mad at my parents and the universe for this, they pushed him to do things and he became some Chad, they just let me rot, I hate my life so much, I don't want to live anymore, I just can't stand it, I can't belief how my parents messed up this much, how they let me become what I am, I'm so jealous of my brother and I just want to shoot him in the head.
