Surrender Unbridled Emotions

I have learned that letting go at times is the hardest thing to do. 
At least for me, sometimes hanging onto the past experiences that have impacted me the most and that have left me with some negative images upon the screen of my soul, I tend to think back on and revisit, more than I should which gives to much life to a dead issue that has been a long time ago. Simple answer for me to remember is to just let it go.
