Most of your problems can be solved through forgiveness.

Forgiveness is an underrated superpower that all humans have the ability to execute at their own free will. It alleviates the burn of anger and pain, which torments you for a lifetime and can be a necessary step to your healing journey.

Humans never proved to be perfect people, and they will hurt each other in so many inexplicable ways; they have in the past and will continue in the future that's human nature. They have free will to choose to do evil, and oftentimes, they'll do evil. You, on the other hand, have the power to be better and to forgive them.

Though people won't change, you can choose change.

Vengeance will be served, mind you, but you dont have to be the executioner. Have peace.
