Hi again Niall,
here is a link that will help you to let go of any negative emotions:-
Your Resistance
Just stay consistent - a little each day, and learn to unemotionally observe. You can observe anytime a negative or anxious emotion presents itself. It is coming to the surface, giving you the opportunity to let it go. Until we learn how to do this, we resist, supress and hold on to the emotion.
As you let go of these hampering emotions you will become more and more free. Be gentle with yourself. Breath deeply a few times before you meditate and if you have time, once a week, enjoy a long soak in the bath with about 3cups of Epsom Salts (Magnesium Sulphate) prior to your meditation.
We all have the peaceful place within us. You just need to let go of the burdens of negative emotions and you will feel lighter and lighter
I wish you an abundance of peace and joy
