That's so incredibly sad.
Some people, like the OP, don't or can't understand that certain words can affect someone and when they're exposed in that environment time and time again, it really hurts them.
Bit of an old skool mentality, especially in this thread. A lot of boys (boys, not men) who try to pass off hurtful words as 'banter'. To me, banter is a way of covering up your own insecurities but trying to come off as the 'tough' one.
Mental health is no joke. Would you tell anyone who has served in the armed forces and suffers from PTSD to 'man up'?
