Goodnight, why must this world be so evil I hate seeing good people having terrible things happen and being depressed

Guys I’m crying my best friend is going to kill herself and I have no idea what I can do she said it’s because she doesn’t want her dad to marry his girlfriend because she likes her dads girlfriend and doesn’t think he deserves him and said if she does it she might not marry him I don’t know what I can do or why I’m putting this in here I’m just so sad

1 step plan to make your history teacher disappointed! Simply say "Whoever killed hitler? That guy definitely deserves a medal!"
