Depression predictably results when your fear of admitting to a mistake is so great that you persist in maintaining an intolerable situation. Acknowledging that you made a choice that you would now like to change can free you so you can move your life forward. In your depression, you may berate yourself for your errors.
But if you give yourself permission to realize that a wrong choice allowed you to gain experiences you otherwise would not have had, then you can stop beating yourself up and get on with your life.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
