I did something I will regret
Why did you do something you'll regret?
I was driven to because I wanted to do it so much
It's okay to regret things when you make a mistake. Next time, how about you carefully consider your actions before doing them? That way you won't have to worry about regretting them later.
That's the first time I've heard someone saying it's fine to regret things.
Regrets are a natural part of life!  It's inevitable that everyone has some at some point.  Just learn from them!
