I'm the eldest, yet both my brothers have accomplished many things in life, they are both super friendly and outgoing, their birthday parties had many friends, high paying jobs, trips around the world, practice sports and are good, beautiful and successful partners. In short, they have the perfect 'instagram life' (I know, I know, nobody has a perfect life, but you get my meaning right?).
Don't get me wrong, I love them and wish them the best, but my homo sapiens brain will inevitably compare with them and thus feel like shit. I have a good carreer and that's it. Single, no kids, I practice a sport but I'm mediocre at best. The last birdthday I celebrated I must have been 11 y/o. And currently hold 2-3 friends.
Not really asking for anything, just venting and see if someone relates or has any advice other than "don't compare yourself to others".
EDIT: Thanks everyone for your time and insights. They have been very helpful! keep them coming.
