I've typed the word nerd or nerds so many times the n, e, r, d, and s key symbols are nonexistent on my keyboard
Is there a reason behind that?
Yes, I hate nerds a lot
Everyone is a nerd sometimes, or in some way. You want someone making fun of you because of a subject that you're good at, or a skill at which you excel. You'd feel better about yourself if you spent your time praising someone for these things, rather than making fun of someone for no good reason.
Nah. I'm depressed. Life isn't fair.
Do you feel this way a lot?  If you feel like there is no use in trying, and that you are resentful of people who do try hard, then maybe you should talk to someone about it.  It might be your brain playing tricks to make you feel depressed when you have no reason to be, and this can be treated.
