Self-harm, suicidal thoughts/attempts & eating or mental disorders & so much more, are not things you can add to your punch line. These things shouldn't be joked about or looked down upon. Because its idiots like you, that make these people the way they are, all for a cheap laugh. You think it's funny? Try spending a week in their shoes then see how funny it is. If I ever hear someone disrespect or joke about someone's disorder or diagnoses or the scars on their arms, I will instantly lose all respect I ever had for you & don't think that's something you gain back with a quick apology, because it's a serious matter & it doesn't consider your disrespect.
