Hi, I’m 16 and my life is technically perfect,

my family is great, everybody agree on the fact that I’m smart, I’m privileged , I look ok and I succeed most of the things I do , i have a bright future wether it is in a university, as an actor, musician but…
But I’m sad as **** and i think it is mostly due to my lack of social skills and my « forced » loneliness (I can’t rely on a solid social socle )
, I have friends at school but I don’t matter that much for them (but they do for me) I’m the nice side dish you never invite to anything
Then I realized I just couldn’t make new friends, I’m unable to create any connection whatsoever with anyone if they don’t do it for me (I only love extravert for this reason) , I can respond well and I don’t think I have social anxiety, I’m just unable to initiate anything (and I’m also an overthinker) I don’t text anyone and I thought for some time that this loneliness was my fault, « I don’t mark people enough to go to their parties » type of reflections because every time I gather all my strengths to start something (it happened twice) it worked surprisingly well so, it might be my fault ?
I recently fell in love with a person that barely considers me as a friend because she talked and was nice to me twice yet I can’t forget her
I’m not writing this to find a solution, I’m lucid enough about myself to hope that , but if possible a little advice or a name to put on this inability to initiate things would help a lot my overall state
Thanks a lot for the time you took reading it
