wreck your head

This is when something annoys to the point that you feel like your head is going to explode i.e. complete frustration

That Crazy Frog song wrecks my head.

Don't wreck your head over it

Don't overthink it. Don't be petty.

If someone has been nagging you about the same thing over and over like...

"You already have 6 different types of flour, why don't you use the ones you have before buying another one?"

Short answer, "Don't wreck your head over it".
