Regrets , past unresolved failures or missed opportunities, guilt or shame are all faces of the same coin that inhibits us from truly expressing who we are.
Self love can only spring from a place where we understand our past and resolve it without going into long sessions of trying to find why.
We can achieve closure by recognising our regrets and understanding that they are a burden to us. Imagine you are carrying a huge boulder on your back and trying to run uphill?Even a short journey will be painful and will exhaust you. Similarly your body and mind will carry that boulder of regrets, missed opportunities and failures unless you find a way to remove them.
