Regret

Regret is an awful burden to carry around. It's also a bitch to rid of. Just when you think you're clear of it, it comes back with a vengeance...Regret....

It prevents you from moving forward.
It saps your strength and distracts you from living life.
It lingers because it is focused on the mistake you'd wish you never made.
It lives in the past but occupies the present.
It's about "If onlys..." (If only I did it differently.)
It'll go away when you accept your mistake and forgive yourself.
It'll take time.
