When you feel uncomfortable think back to a happy time. A really, really happy time in your life. Go back as far as it takes, to a time when you felt so light you thought you might float.
Do you remember it? The carefree feeling? The acceptance of the moment, of yourself, of life? Feeling unfettered by thoughts of the future and oblivious to the past?
Feel it a little longer... slowly... and smile inside.
There. Very nice.
