Hi nahgem --
depression is a bit tricky. By that I mean that it can be related to a lot of things, not just your nana dying, but genes... You mentioned that your mom and dad are alcoholics... They probably are low on b12 as a result, and being low on b12 can be a hereditary trait. My mom had pernicious anemia, and I have a tendency toward low b12.
That wasn't very clear, sorry. I actually have some brain damage from extended low b12... While my doctors were prescribing antidepressants, my low b12 was causing permanent nerve damage.
Here's something I learned that has helped me: lines on fingernails tend to indicate low b12... A sublingual b12 supplement can be very useful and make a great difference.... When I began having regular shots, I was totally amazed at the difference they made. I haven't switched to sublingual lozenges yet because the injectable cobalamin is so cheap and i'm so financially challenged :d
but I think the sublingual is very reasonably priced at walgreens...
The old way to diagnose a need for b12 was to prescribe it and if it made a difference, then the doctor concluded it was needed...
