i'm sorry that that happened......something also embarrassing has happened to me and i felt the same way.....i think finding another way to relieve that shame and embarrassment would be a better idea.....i think you need to throw out your blade and find another way to make yourself feel better....i know that it's hard and that you don't want to, but getting rid of your tools is part of the healing process......maybe writing or journaling would work.....i like putting my thoughts of paper.....maybe using relaxing lotion would help too.....in the hospital someone told me to write a list of at least 5 things for each sense that i find soothing.....so i wrote down things that are soothing to me and when i have a hard time i imagine those things and it helps me stay grounded.....hope this helped....if you wanna talk, please feel free to message me

First of all, you have NOTHING to feel ashamed of. Don't be too hard on yourself for this, you are not to blame in any way.
Second, I'm sorry that the people in your class are absolute IDIOTS. People like that are just cruel in my opinion and get pleasure from other people's pain, suffering, and embarrassment. You are a MUCH better person than they are, and you won't have to put up with them forever - there are some good/nice people in the world, even if it is hard to find them at times.
Just a suggestion, maybe don't carry your blades around with you, or as @valgal18 says, throw them away. I also agree that writing helps a lot - it is a great escape for me. I know it may not work for everyone but it's worth a try.
Please message me if you need/want to talk, my inbox is always open. Hope things improve for you soon X

What an asshole. That person is just a bully. Its their fault not yours. It just makes them look like a bad person.

That blows. I know I had a kid to that to me and later would make comments bc I was siting behind her. She would say I smell I am fat and other really mean things. Most of the time I would just sit there as the class smiled and giggled at the comments. I felt like shit. I told the teacher and she started to watch for it, and one day she was caught and sent out of the room for the comments and she yelled really load all the way down the hall way a whole bunch of horrible stuff about me and the class just laughed. then they would be texting and would look at me and laugh.. Needless to say when that girl came back and made the same comments I stood up for myself told her to get a fucking life. she got pissed stood up and punched me and boy that was her big mistake, Im a boxer and once she hit me that was it.
What I learned after this was if I dont care what they say they dont get the power over it and if they dont make you feel crappy then they will keep trying but if you dont give in they give up. When you give them the attention and show it bugs you they get the power.
Bullies need that power... sadly most dont grow up and they become low lifes and will see they have no friends, and all the people around them really just are there so they are not a target. there is always a reason why someone bullies, and sadly some never learn to grow up... Dont allow them to bring you down hun really dont. I know the words hurt I know the laughing hurts, really I do but they want to drag you down dont let them!!! be yourself dont let anyone drag you down!!!
I know this might sound stupid but really they are wrong. they are rude they look stupid, they will get no where being that way. Be the better person and dont run away I know its hard but just block them out they dont matter, and if they ever pull your chair out from under you again. tell them oh wow... good for you... you have no life so you hurt people wow your going no where in life try growing up. And they will comment back but you can keep at the comments back or laugh at it. yes it might hurt you inside but laugh on the outside smile. That drives them nuts! trust me I did it and that drove them crazy! they called me fat yet I had abs.. I laughed and smiled and that pissed them off. I didnt let it bug me, even though I felt horrible they where saying awful things and dragging me down. but they left me alone in my last year bc I never gave them the reaction they where looking for!

Are you fucking kidding me? Another thread, another crass statement from bobthebelcher. Must make you feel better to be insensitive and an ass at other peoples expense.

stay of this fucking comments okay this is to help us and if you cant then you need to get off this site you might think it's funny to sit there and antagonize people having trouble think again we go through actual problems and this shit just makes it more completed we are fighting a constant battle and comments like yours push us to the losing side
