Have you seen a doctor who knows about environmental illnesses? My allergy to fish caused incapacitating headaches, the worst kind, they say, until I was tested. No more fish, no more headaches. Eating beef cause the "sham rage" and tears. Not bothered with that any more either. Of course depression goes with that- when a doctor doesn't know why it's happenind and you can't stop it and consider suicide, a person would be a fool NOT to be depressed. Go to an allergist who knows about food allergies/chemical allergies (as petroleums).
