Our past and present are intimately linked by our memories. Our memories are heavily influenced and based on feelings we had surrounding an event or experience. These experiences may be impacting your life right now, even the ones that might seem irrelevant or insignificant. If we don't become aware of this connection it will keep affecting our future, which over time can cause us stress. Prolonged stress can manifest itself in physical forms, including illness, lack of energy, problems with sleep, headaches, depression and anxiety. When you are mentally healthy you are able to handle life's challenges.
