You are mistaking Stress perhaps with depression. It is 99% more likely that a physical problem is the root problem and that is causing the depression. Thats what depression is. Something is wrong with your body and your brain is sad about it. You dont just get depressed for no reason and then your body breaks for no reason from that depression.

Your brain is part of your body, so that’s a fairly tautological claim.

Perhaps you have Beriberi and the extra thiamine from keto foods like the meat is helping?

looking into it, thanks for the pointer!
