Start seeing yourself from their (people’s) side. You will get the answers for the way they trapped you, loved you, hated you, treated you, abused you. There will be 2 or 3 probabilities for all their actions and behaviours. And then, you don’t have these questions of why did they do this to me, why do they love me or why am I so important to them. You will get to know their reasons for all of them. And then you have only few questions to deal with.
Should they be in your life? If yes, what level of interaction and transparency to be maintained. How much access you will want to give them to your life? If no, how well you will avoid them or slip out from their life. Why is it important to do this activity? To free the bandwidth on your mind and get better constructive at your work than wasting your precious time on unworthy, unwanted people or things. Or to keep yourself connected to genuine people who really care for you and love you.
