you need to find a new hobby...take up a religion if u don't practice on already...you need to put 'stock' in something worth while, something that would make you feel like you are who you are.....really, i would assume that when you looked at your S.O that you should feel whole, maybe you need time to think about your life for a little bit, maybe even away from your S.O for a bit........
