You could always live in constant denial.

I constantly deny my desires to murder children..

What?

hahahahaha i've never been to Baltimore...but i live the same situation with my small fuckin town!!

What about Baltimore was so horrible?

I saw something about a Mars project once... think it was called Total Recall... there you could get your mind erased under very nasty conditions!
Ps. I gratefully accept Love

i think hypnotize doesn´t work
it better if you filled the bad memories with good memories

Walk to a bridge with deep water.
Take hold of this tempest of misery as it were a heavy stone.
Release it to the depths.
Walk away a lighter spirit.
