Getting stuck in the past is one of the common problems people suffer from. The past, present, and the future are all separate and not easily interchangeable. They can be if you are grounded in the present.
However, most people live according to the past. It’s what they know and have experience. However, the past is over. You can use experience to help you make decisions, but things change, people change. Relating all current decisions based on the past isn’t always a good course of action.
Many people go through their life carting all the baggage of their past. Most of the time, these are negative memories and feeling. Why is it usually negative? We remember the bad easier and fast repeating it. But we are not the same person that we were then. How many people experienced thing decades ago and act as if it’s the proper guide for the present?
Thoughts can trigger emotions. So when we live with this baggage, it affects our condition. It creates depression or anxiety.
Please my friend. Get out of the post if you are stuck there. It’s over and you are a different person than you were them. Love and live in the present.
