I've noticed a lot of threads about kids being pissed off at bullies and wondering what to do about them. Well listen up kids, because I'm going to give you some advice that I wish someone had given me years ago.
Whatever you do, don't convince yourself that you're miserable because nobody "gets" you, and don't ever act pathetic as a cry for help; if you're still in grade school you can bet your ass nobody around you even knows the meaning of the word 'pity.' If you go around stalking the halls of your school with your eyes to the ground, you're just broadcasting to everyone around you that you're going to be an easy target for them to take out their own frustrations on.
And no, people won't just stop picking on you if you ignore them. They'll start to see you as their personal punching bag. No, they won't stop picking on you if you choose to fight back, verbally or physically. They'll just want to get even, or to have the last word, and you're going to demonize yourself to people (teachers, etc.) who would otherwise be there to help you. Once you put it in peoples' heads that you're vulnerable, they're going to exploit that fact and it's going to be way harder for you to pull yourself out of a rough social situation. That doesn't mean it's impossible though.
So what do you do to keep bullies from picking on you? Smile more. Seriously. Act happy, even if you have to fake it. The power to be happy is a kind of strength that few people would try to contest--you can't exactly prove you're happier than someone by beating them up or calling them names. Really, if you look like you're in a good mood then people around you will naturally feel more at ease. They'll start to like you more because they'll feel like they can trust you and talk to you. They may even come to respect you. Eventually you're going to find yourself actually feeling happier. I've heard some say "just be more confident," but that's only a shade of what it takes. You can only make that happen as a result of improving your mood. You can't simply pretend to be confident; it tends to make you look like an asshole and it's easy to see through, especially for others doing the same (which is probably going to be most people).
Obviously, if bullying you becomes the norm it's going to be much more difficult to get people to stop. Like I said earlier though, it's far from impossible. Make friends with them. I'm serious. Of course, you can't be too obvious about it. Do NOT try to ingratiate yourself with them by giving them things; they're going to see gifts as tribute rather than tokens of friendship. All you have to do is be cooler than they are. Just a simple "hey what's up?" when you pass them in the hallway will go way farther than you'd think. Don't be submissive, but don't try to make them feel insecure either. That old piece of advice, "don't stoop to their level," is kind of bullshit, but only kind of. You have to be able to understand each other, which means somehow getting them to understand you. Though like I said before, that won't happen if you're just trying to pull the pity card.
There's also the issue of respect. Do you respect people who don't respect you? Of course not, and they won't respect you if you don't respect them. Don't tell yourself you don't need their respect, either; if you really think you're that high above them then earning it should be trivial, right? Don't be a poser. Posers are easy to pick up on, and if they see through you they're only gonna think you're weaker. Do your own thing, and respect others who do theirs. Don't be annoying or in-your-face about yourself, but don't be an enigma either. If someone asks about you, tell them.
So how do you just "become happier," beyond tricking yourself into it? Smiling as much as you possibly can is a good start. Plenty of research has suggested that smiling literally makes your brain release those feel-good chemicals that'll lift your mood. Also try taking better care of yourself. I dunno about you, but I always feel better about the day ahead after a nice hot shower in the morning. Get enough sleep. Eat right. There's a lot more you can do than all that super basic shit, but that's a deep enough subject for a topic of its own.
