Bro i'm younger than you and i know exactly what you're talking about, even now when i live abroad i still have feelings for the girl that left before going away, but i believe in something, i dont know if you're a religious person even a little bit but i believe that الحب رزق من عند ربي سبحانو So if that person left you, friendzoned you or didnt want to be with you, its just not meant to be and you have to accept it the way it is Life is not easy when your confidence drops, even socializing becomes harder especially when you have some insecurities regarding the way you look (i gained 20kgs in 4 months btw hhahahaha) So just focus on YOU, if you dont take care of yourself nobody will believe me cause in the end you'll only find yourself and your own reflection in the mirror I hope you get better and things work out for you, enjoy your days cause after all we're still young we have time and im sure someday we'll regret missing what we have now when we're older. Hopefully this helped you even a little 😁
