Who Rules???

You know sometimes when you feel that you have a lot inside that needed to be said, yet you can never find the perfect words that could help you express what you want to say, well! this is exactly how I feel right now, I feel that I have so many things to say but then when I try to say it I can't, I wonder why??? this makes me wonder, do we have some sort of a Langue that is tucked deep inside us and only our heart understands it? could that be?? I wonder!!!, I wish I could understand my heart more, sometimes I feel that it is a battle between the two of us, I know it's part of me, but my heart says something but then my mind disapproves, what can I do, to make them both happy, when I listen to my heart, I end up hurting myself, and when I listen to my mind same thing happens, who rules?? the heart, or the mind, or both? I wish I could figure that out, that would make my life easier. Amazing, amazing, amazing how even us, can't understand ourselves and we expect others to understand us.
