Its obvious that you don’t fit in with your peers. It doesn’t help to hear that, because it doesn’t make things any easier, but it’s hard to feel comfortable around people that you have nothing in common with. And at you age, with your intellect, that’s obviously noted.

Sounds to me like you have a bit of a social phobia. Which I think comes mainly from the fact that you are (dare I say it?) superior to those around you? I’m sure if you found people you can relate to better you might feel more comfortable socially.

I think the fact that you feel like you are living in this daily cycle that is bringing about your short temper, And maybe you are just naturally a bit of a loner. I usually lock myself in my room as well because I just don’t like dealing with my family. It’s not abnormal.

As for the cycle thing. I completely relate to you on that. It’s hard to see life as more than just your daily routine. However, my advice to you is to try and find something to spice it up. Right now, however, you are too young for a job, but what are your plans for the future? It seems to me like you are the type of person that needs constant change and intellectual excitement. Not really sure what your interests would be, but I know that you wouldn’t be happy with a typical 9-5, because I know that I wouldn’t. I’m sure if you talked to your teachers or counselors or something, they might be able to find a program for you to get into. Something that you’d enjoy doing that will make life seem less mundane and routine. That might help you break out of this cycle. Right now, however, this cycle may not end, and you may not be able to sit down and say "phew, I’m done" until you get out of school. But the opportunities that you will have by putting in all this stress and shit will be the reward you are looking for.

It’s sad that you are questioning if life is worth the effort at such a young age. I know where you’re coming from, but you really wont be able to get those answers until you get older. Which really sucks to hear, I’m sure. But like I said earlier, try and find a program/internship/volunteer opportunity that you’d enjoy. Finding happiness and diversity in a cycled life is part of our jobs on Earth. The wake up school/work home repeat becomes a given, its finding the opportunities in life that make us enjoy our lives more.

If you want any help with anything, anyone to vent to, or whatever you can email me at emptybox1988@yahoo.com. I really feel where you are coming from and I think you have great potential to be a strong role in this world and don’t like hearing you question the boredom of life.

Simplicity in itself actually
Condense what you carry in the hallways
Organize things in your locker so the stuff for your next class either practically or literally falls out of the locker each time you open it.
Pick a book that NO ONE ELSE in the world would read (I picked Dante’s Inferno) when they ask what you’re reading ignore them (This sounds absolutely retarded but it works great)
Make small comments under your breath or just loud that those terrible people can hear you
(BE ABSOLUTELY SURE THEY WOULD MAKE THEM FEEL BAD)
Alert teachers to everything they do (I keep a journal and I get extra credit in Spanish just for showing up!)
Make some friends (Kind of hard to just say it) be absolutely sure they wouldn’t betray you.
Go places you think you might make friends (I met some of my best friends in a LEGO robotics club thing at our school and another I met because of a line from "The Simpsons Movie")
Something I forgot to add to the top (This will make me sound creepy) The reason you need to condense is so you can move quickly and efficently (Think ASSASSIN) I follow kids I don’t like through the halls (This is where my journal come in handy) take notes abut social interactions, things that piss them off, and social connections.
Remember, as my father says, "Never hit another man out of anger, unless you’re absolutely sure you can get away with it," Learn weak points of the human body for just such small "violent" interruptions
Nothing is wrong with you
Every human being is their own person (That is so original I could just throw up)

Remember though that no matter hat happens YOU ARE ABOVE THEM

PPPPPPS In retrospect I am a coin with these things on some days I’m as immature as the people I hate but I love to read my books and zone out of this world of ours. On the other hand occasionally I am more of a puppeteer where I can use my enemies emotions against them while retaining a laid back aura.
