Change, what is it, and how do we create it? 

By definition, change to make the form, nature, content, future course, etc., of (something) different from what it is or from what it would be if left alone (https://www.dictionary.com/browse/change)

All of us, constantly create change.  We get up and change from being asleep, laying down etc.  We create change when we do anything.  Habits create familiar, predictable changes in our state and routine to match what we have agreed to experience in our life.  The routine, the known, familiar, expected actions that make up life.  

Words have a vibrational power to change your world. How?
The thought behind the word changes your body chemistry.
As simple as black and white. For many, each has a different feeling; black dark and heavy, white light and expansive.
Love, Joy, Peace infer a calmness and excitement which raises our vibration.
Sadness, disconnect, loneliness feel and therefore change our body chemistry to denser, heavier and likely depressed/compressed body reactions.
To heal, live life more fully and creatively, lighter, expansive feelings create the space for this to happen.
Your thoughts, create the vibe that goes out into the world, drawing to you experiences that match or a similar.
Now, you have choice. You and entirely you have the ability to control your thoughts. As you become more aware of your thoughts, feelings and action, you are given the gift of conscious change - what do you want to feel, be and have?
How, in the moment to you cut off so to speak and redirect the heavy memories, feelings, fears, etc.
Notice them!
* Thank them for bring your attention to something that wants to be healed.
* Tell the feeling that the adult you does have this under control and you CHOOSE to be in the moment and see, feel and be the positive aspect of the situation - choose the silver lining component, the blessing in disguise etc.
* Breathe deeply refocus in the now. Literally in that second to second moment and consciously see, feel and be the silver lining.
* Step into the positive power this provides. Own it and continue doing what you are doing with conscious, chosen, empowered choices fr feeling, action and response.
It gets easier with practice and yes, if you feel the past has a massive hold over you, support will benefit.
