I used to be bullied when I was younger, the older kids just loved to tease me. But it does get better once you take care of it. They stopped bullying me because I stopped showing emotion when the teased me, or several times, shoved me into a wall.

Depression is something everyone goes through, last year I was super depressed, everyone made rumors about me and it was horrible, but I graduated and now I have a bunch more friends who help me get through stuff like that c: Just remember your not alone. Also if you have suicidal thoughts, just remember Suicide is a permanent solution to a temporary problem

I was bullied when I was in middle school because I never stood up for myself. I was small and quiet, always focusing on my school work. I was also very young for my grade since my birthday is in May.
I personally disagree with the "ignore them and they'll go away" tactic. I always ignored those boys. I never showed them that their teasing got to me, I even went along with it sometimes, though I don't know why. I hated going to school because I knew that they'd be there. I came home crying almost nightly. I was in the principal's office 3-4 times a week but I was never in trouble. I was always talking to him about what those boys were doing. He never did anything beyond slaps on the wrists ["Now don't you do that anymore!"] because he wanted to seem like a cool principal and it resulted in my suffering for years. You have no idea how much I'd love to put him on the spot for doing that, to question him and tell him about all the hell I went through because of how he wouldn't punish those boys.
Nothing changed until one boy drilled me in the thigh in a game of dodge ball. He used excessive force and my leg was black and purple when I sat down. Later he got four other boys on his side to collect balls and they all five aimed for me once they all had one. I ducked and ran to the side and missed all of them, luckily, but the teacher didn't do anything about it. That night I told my folks about it and my dad got mad, "Okay! No! I'm done with this!" He got up, pulled out the phone book, looked up the boy's parents, and called. He asked for the boy and said, "Okay, listen here you little punk. If you mess with my daughter one more time, I'm going to find out where you live and lock you in a closet!"
No more problems after that, at least from him! Unfortunately, we can't do that anymore for risk of jail.

The boys would also race me to first period. They'd make a game out of it,, even though my doing so was because I didn't want to be late to any classes. I took school very seriously. One day one of the boys went to trip the other but he jumped over his foot. I was right behind him and wasn't able to react in time. He tripped me and I came down hard on my knee caps and my books went everywhere. Being the coward that boy was, he ignored what he'd just done and ran off. I approached him about it later and he told me that I needed to learn how to walk. I should have punched him straight in the face for that.

I got lucky and was split up from those boys once we got into high school, but my thoughts are still the same:
DO NOT put up with it. Stand up for yourself! While I can see why the "ignore them" tactic may work, if it doesn't, stand up and do whatever it takes to put a stop to it. Kids are mean and some of them just need to be knocked off their high horse and shown that it's not okay to bully. If you've tried talking to your principal or whatever highly ranked individual is in charge of the place where the bullying is happening and they won't do anything, have your parents to directly to theirs. Sometimes the kids put on good faces for their parents but are little snots outside the home. In these cases, alerting the parents and explaining what the kid has done will take care of this.
If the parents are snots too and refuse to do anything about their snot offspring, stand up to them. See if there are teachers who will stick around you to deter the kids and let the snots know that you're not going to put up with the bullying.

I promise you that, in the future, those punks will mean nothing to you. Be the bigger person, but don't be afraid to get involved. I don't personally have depression but It's better to stand up for yourself now than to let that depression get worse as you grow up. Self-respect and self-esteem are extremely important and I promise you that those will increase if you stand up for yourself.
