Welcome Stuart,
Well done with the meditaion and grounding work. Its very difficult at first when we experience a breakup. It is the ego that causes the pain not the real you! When we find ourselves alone after a breakup our ego's go to work...usually things like self-worth, am I good enough, what did I do wrong, what did they do to me, and on it goes. We try to make sense of the situation and It can be hard to understand it all...However remember this is the ego at work, It survives on fear and fear alone!! We only ever experience two emotions, fear and love and they come in all forms. The analytical mind (when we try to make sense of all) fuels the ego which leads to dis-ease and we become this person that is not who we really are. You are a being of love and light and you are here to help understand yourself, who you really are, this is the same for all of us and our journeys continue...
all you need to do is to be of love and value to all. This is a major key to understanding soooo much.
I am proud of you that you are searching, looking for what is missing, you will look back on this and see the positive gifts you have learnt...well done my friend.
Love always.
