I wish I could Explain

Sometimes in your life you feel the unexplainable. Its a horrible feeling really. You walk through your days unhappy but unsure why and it is not about anyone else in particular really but rather just a horrible feeling that wont go away. Well that was me last night....and its carrying over into today. "Mr Big" asked me if it was because of him but it didnt seem like my answer of " of course not" was sufficient. Why am I like this? Do i have some unexplainable need to submerge myself in memories that only cause me pain? I wish i could tell you, I wish I could explain but unfortunetly there is really no thought process its only a feeling of.....well....the unexplainable.
