People generally think that if things had lasted longer it would have been better. Things you lost must not be cherished.
Things that were taken away from you were taken away for a reason. Longing for something or someone who is lost forever and thinking of the times in the past for a long while isn’t healthy. When you do, don’t expect people who know you in the present, people whom you don’t appreciate in the present to stick along.
If you are living in the past, you should stop immediately. If you know someone living in the past and not ready to move on, let them go. You need people who like you for you not people who compare you to the old ones they have lost and always look at them with fondness.
Nostalgia,I hear is the best liar. What you think about those times becomes what happened. It may not have been that way at all. Let go of the past. Let go of the people in the past. Just let it go.
