>>5 thx for the advice. Going back to the post, I can kind of understand what u went thru, since I too, have smart cousins who have gone to elite schools and are now completing their masters at Ivy league universities. My point is, yes they are smart, yes they are high achievers... but that is by no means a reason to doubt yourself when you're with or without them. Everyone is born different, it's natural and completely normal to have different aptitudes. They may excel in academics but may have a cold personality. You may be bad at general knowledge but you deeply care for the people around you which they don't realize.
I'm guessing you're a teenager, since you're having these thoughts (it's completely normal btw). It's a wake up call for you to improve yourself. Something like "hey, I need to up my game if I want to protect my self-image and pride" kind of thing. But. But. BUT. Don't rush improving yourself. Take your time, and after a while look back. You'll see that the mistakes you made were beautiful ones you won't regret making.
Remember, no one can make you feel inferior without your consent.
I wish u success in improving yourself :3
