Suicide

during teen years, losing someone dear to your heart or having the feeling of loneliness can cause them to consider suicidal thoughts. just think about your surroundings, family, friends, relatives. people in your community that actually care about you. if you ever feel down, take a new path in life instead of following the one your currently on. example; change your personality to be more outgoing and enthusiastic, so you'll make friends much easier. learn to not always depend on others as a life support, but be strong and independent. put it all in the past, and look toward the future.

EDIT: and imo, suicide isnt only a horrible way to go, because its homicide on yourself, and the way i think of it, your also killing your future kids. because for all we know, you're gonna have kids in the future, and cutting your life short wont allow them to exist. (sorry, i always look into the future)
