I have had many friends and even family who have killed themself for how the world and people treated them and i know what it feels like to want to kill yourself but it is no the answer.

Try to not be mean. Even the smallest thing could hurt someones sef-esteam, their pride, and make them feel very unwelcomed in this world. if you see someone degrading a person, intevign, you might just have saved that persons life.
