The Two Modalities and Split Personalities

Do any of you who have a part of your chart which is all connected by water and earth aspects and a part which is all connected by fire and air feel like you battle to find a balance between two sides of your personality? With me, I have a water ascendent and sun, and also venus and pluto which gives my personality a certain water 'backbone' if you will. This side of my personality is further aspected by jupiter and uranus, and neptune, all of which are in earth signs.
But then there is another side to me. I have moon, mercury, mars and saturn all in fire and air signs, so the moon side of my personality craves a different kind of thing than the sun side of my personality.
Because of this, I often find myself in the middle of doing something like playing guitar and then having an overwhelming sensation of being a piece of shit, and I get motivated to do something practical like clean my car and then I feel rather like a banal zombie.
I have to try to get over this by accepting the fact that I am never quite as sure about what I am doing as I would want.
Anyone else have a similar split?
