Don't live a lie. Live the truth. Set your spirit free.
It can be very challenging to forgive and forget when someone has hurt you. Forgiving is difficult, but forgetting can be even more challenging. If you can't forget, it might be more helpful to think of it as detaching or letting go so that you can make space in your heart to embrace something new.
You can't expect your job to fulfil your life. It's only a part of your life. Even wonderful careers are not enough to give your life meaning. It's a combination of factors.
