If you haven’t already, you will experience grief (likely several times) during your lifetime. Grief comes as a result of many experiences. The most common one is due to losing someone who we care about, but we can also grieve breakups, divorces, etc.

That feeling of regret sinks deep in your gut and almost makes you sick to your stomach. It creates anxiety, doubt, fear, and even panic. It's like a tidal wave you can see coming but can't do anything about.

Your brain will grab hold of that memory and give it the power to interpret future interactions and relationships. For example, suppose another person hurts you by continually lying to you. In that case, you could find it difficult to fully trust or believe anyone.
