Throughout my childhood and teens there was always someone that would manage to say something cruel, to shake the little self-esteem most kids have during those years.
Sometimes we can almost image those cruel things being said that in reality weren't due to the horrible feeling the verbal remarks left us with.
I'd be lieing if I told you I never felt that empty that hurting myself was a thought.
Easy from my end to say, but try real hard to ignore such remarks, so often it is coming from some insecure person who is frustrated with their own lives, even feeling that it is them no one likes, so they reverse it to you or someone else, they hate their metaphorical reflection they see of themselves in the mirror.
Bullying is another form of this sort of insecurity, finding power within themselves by stomping on others.
These are the people that are in desperate need of help.
Try to keep in mind that such mean remarks are untrue, detach from such people. Back in the day I would resort to being "the quiet one" trying to avoid the pain or allowing those to get the satisfaction that they hurt me.
Believe me there is no one in the world worth trying to OD or harm yourself for.
Hang out here, vent when needed, there is always someone here that will reply.
Sorry to hear you are going through a rough time.
Please take care,
