Zach had a lot of similar problems from low carb which he cured by following the tips above so I'm sure you can take his advice.
I just wanted to say I'm really sorry that you havent been well and I feel your pain about the appearance-induced agoraphobia. You may not look your best right now, but that it's not going to last and I'm sure you're still beautiful. Anyway, strangers on the street won't know the difference
Make sure you tell your close ones what's going on with you so they can give you support.
PS. Low carb wasn't optimal for me either.
"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."
