I'm so stupid.
I just turned 15 years old a few days ago, and recently I've been thinking about my future a lot.
I won't have a good job, I'm really really really stupid, my little sister who is 2 years younger than has to help me with my homework. I'm 2 grades behind in math, my sister is 2 grades ahead. And she's smarter than me.
And I have no friends, nobody wants to be my friend, I'm boring, not funny, I'm nothing special.
Girls also hate me.
I have no talent, everybody in my family has a talent.
Mom can sing, my sister can draw, and dad makes people laugh.

My parents aren't proud of me, I'm a disgrace to them. Yesterday my mom was talking about how talented my sister is, she never does that to me because I'm worthless. Nobody gives me any attention, I know I sound like an attention grabber but I really want to be noticed but how am I going to be noticed, I'm a nobody.

And I'm so ugly, I hate my face I want a new one. I'm skinny, short and whimpy.
and yesterday I wanted to mow the lawn for my dad, and he was showing me how to start the ride-on mower and he explained it to me like 4 or 5 times and I just couldn't get it and he got frustrated and called me a dumbass, and that hurt.

Am I going to be a failure for the rest of my life, am I a failure?
