gaping at a hole in my being... T_T

i know this is weird, but have u ever felt that hole in u that u cannot explain?.. sometimes u feel whole, but most of the time.. u feel it.. a hole in your whole being.. its as if a part of u is missing and u cant seem to find it.. i know someone who feels what im talking about, (its a good thing, i guess, it means that im not loosing my marbles!!) do u think im normal? or is it normal to feel this way?
