Dude, I'm going to be repeating myself but...
It will make you miserable forcing yourself to go out and do things you don't enjoy. Have you thought any more about trying to meet new people who might have the same interests as you? Or even getting a part time job in a cafe or something? It would give you a bit more structure to your day... Sorry, I feel like I'm being really blunt!
"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."
