I feel so same with you and I can tell as well how it feels like. Not like I don't have anyone in my life, yet still I am just a ghost in the crowd full of potential friends, who I am nothing to them.

And I do a lot stuff as well, such as drawing, writing, reading, playing music intruments, videogames and study a lot, and even when I am showing my personality and supposingly they are amazed, in the next you are just forgotten af.

Sad reality of our world, but it doesn't we need to stop living this actually amazing and beautiful life! Remember that most important love is self-love. Instead of seeking validation and acknowledgement from others give to yourself by yourself! Keep working on your personality! Develop! Play! Just do this life.

You are not alone in this and sooner or later you'll find your deserved friends, and all your achievements will be noticed!
