Is it possible for someone to know when their crazy?

Very few people in the world are actually crazy and you are not. You are at a difficult time in most peoples lives and you are very hard on yourself. You really do need to talk with a professional not because you smell or think you smell things but because it bothers you so much. Everyone of us does or thinks things and wonder if we are normal or if we have mental problems. Seeing someone who has studied human behavior would reure you that you are not mad. Seek help so that you can continue on with your life and not let this behavior stand in your way. =)
