I think I know the feeling that you're talking about. It's like a blend of disgust and irritation, directed at someone who the sight of just makes your blood boil, for no apparent reason? This is terrible, but I have that with one of my best mates. He's the most amazing guy, but if I spent too much time with him he drives me bananas, and it's because he's too subservient. He's too good, too nice, and eventually it puts me in a state of dis-ease because by comparison I feel hard and cruel (and seriously, if you knew me in person, I'm not like that at all).
Some people who are very vulnerable are very needy and if you're sensitive you feel that need more than emotionally or intellectually. You feel it almost like an energy, and it's draining. I can give and give and give to some people, but not to others, and it's not based on who they are, it's based on what I feel when I'm around them.
"I think the basic anti-aging diet is also the best diet for prevention and treatment of diabetes, scleroderma, and the various "connective tissue diseases." This would emphasize high protein, low unsaturated fats, low iron, and high antioxidant consumption, with a moderate or low starch consumption.
In practice, this means that a major part of the diet should be milk, cheese, eggs, shellfish, fruits and coconut oil, with vitamin E and salt as the safest supplements."
