I understand that one should only speak in the positive, as in "I have beautiful, clear skin" as opposed to "I DON'T have acne" only accentuates the negative. However, still not sure that works...I'll have to give it a try!
Still, I agree with your theory to some extent. I differ in that -although I believe the emotional CAN affect the physical- we seem to manifest these issues differently; some get acne, others manifest their stress in different ways. So why? Genetic vulnerabilties?
I wonder if you have considered testosterone imbalance, trysten? High sex drive and quick to anger? Just a possibility you might consider.
