Nobody should feel ashamed of being bullied. It's not anyone's choice. The only people that should feel ashamed are the bullies. They don't have the right to bother and hurt other people, that's why someone should know.
If you are being attacked or made fun of for any reason, you are experiencing bullying. If its from one person or a group, it's the same thing. There are ways though you can seek help. If it's in your school, talk with a close teacher or guidance counselor. Maybe even go to your principal. It's also a good idea to go who is closest to you, your family. Let them know how you're feeling. If no one knows no one can try to help. Talking and expressing personal things are hard I know, but it's for the best in some cases.
It's important to always tell the truth. Do not exaggerate a problem or story to benefit your side. Lying will never get you far believe me. There are people who care about you even though it may not appear that way. Share your voice for someone to listen. Try a close friend, parent, or someone at your school you can go to.
It's not your fault, try to remember that. The years between childhood and growing into an adult are getting harder everyday in the instant society we live in. Social media is a quicker way to attack someone from behind closed doors. You really cannot escape it no matter who you are if you ask me. But you can fight through it, and if it doesn't seem like it will stop right now, it will when you finish this chapter and move on. Growing up sucks but also is an amazing thing. You can be whoever you want when you have your own freedom. All the events that went on in the past can only make you wiser. You can't really know about something until you experience it.
Speak up and be the voice for the ones who stay silent. If you have an opportunity to make a change, take it. Everything must go on.
EVEN IF YOU TELL SOMEONE AND NO ONE LISTENS, KEEP TALKING TO THEM ABOUT THE ISSUE.
PEOPLE CAN GET DISTRACTED FROM THINGS BUT THEY CANNOT IGNORE YOU FOREVER.
