I think "I hope you are going to be okay" is more accurate then "you are going to be okay or its going to be okay"
I am sure they mean good and are trying to make you feel better, but the reality is, sometimes things will not be okay. Otherwise, millions of people would not end their lives every year. It is very sad and depressing, and i do wish that things will be okay for everyone though, but i don't think its a realistic guarantee
