I think it has ruined my life.
Why do you think your life is ruined?
I don't know the reason why, but something inside me has been changed by it.
I understand it's difficult to deal with life when something negative happens, but you shouldn't let something ruin your life. No matter what happened, your life is certainly not ruined. You can always make changes and move on from any mistake or experience.
You're probably right. It's for the best if I face the challenge.
That's a good attitude to have. Good luck to you on your challenge.
