This is such a wild mix of utter darkness and comedy with just a pinch of wholesome advice (given in the wrong way on the wrong subject but the intent is there).
@kwendy He was going to be a girl in his next life - and realized he was postponing it and could as well be a girl in this life.

On another note - Just jumping in front of a metro train by a station has less than 50% chance of killing you. So on top of the reasons she gave, there's plenty of reason to not do it (that way).
Seems rather reductive towards mental health. "Your depression was entirely caused by a misconception on your part! All it took was my opinion to cure you!!"
edit: oh and let's not forget "Also, think about everyone else! How they feel should be more important to you than how you do!"
@H-san Actually, a little push like that can be enough to prevent someone from actually attempting suicide. It's one of the reasons it's important to take anyone seriously when they seem suicidal and talk to them. Simply talking to them and pointing out things like with this girl how killing herself would also be failing her mom may just save their lives. Not always, but often enough its always worth trying.
