Anger is an emotion that comes from somewhere, just like all other feelings and emotions. But when we have grown up in unhealthy ways and have unhealthy patterns, sometimes our feelings and emotions are not necessarily directed at the right person, or the right thing at the right time, or for the right purpose.
This is where that patience and time comes in. Really dissecting and getting to the bottom of why you are feeling the way you are feeling, how you can handle it with the actual person or situation that is the root cause of the anger or hurt or whatever else you are feeling, is where we ultimately want to get to.
