Your first name of Johna is a dual influence: at times you can be extremely happy, expressive, full of fun, and good-natured; yet at other times you find congenial association impossible, being controlled by self-pity, moods, and depression. This name incorporates inspirational qualities, making you desire outlets in forms of art, drama, music, and vocal expression. Uncontrolled thoughts and emotional upheavals could disturb your peace of mind and upset your finely-tuned nervous system, adversely affecting your health. You are deep, philosophical, and refined, but your extremely sensitive nature causes you to become depressed over any real or imagined slight. If you could express only the constructive qualities and restrain the negative qualities of your nature, you would always be good company. You have a sensitive nature, tuning into the thoughts of others and feeling much more than you can interpret and understand. This unpredictable quality makes it a challenge for others to understand you; you find it hard to understand yourself. You find it difficult to be practical and patient, preferring to act impulsively as the spirit moves you. Physical weaknesses could show in heart problems, or congestion in your respiratory system. Your appetite for quick energy foods could result in high blood pressure, skin rashes, and liver problems.
