Hey there!
This can be an opinion question, but here would be my answer:
This statement should be true.
Telling someone that they will be just fine after they get hurt or just go through difficult times is reassuring. For some people, it doesn't help but for most people I would say it does.
Encouraging someone that they will be fine is also a good therapeutic because it can heal the person and change their mood.
Therefore, the answer should be true.
I hope this helps you.
Have a great day! :)
