Fingernails! ugh!

I can't grow my fingernails to save my life! It's so annoying!

I take good vitamins (best ever, I'm told)
drink healthy breakfast shakes
eat good snacks (MOST of the time)
drink lots and lots of water
exercise on a fairly regular schedule
eat healthy regular meals

And STILL!

It's mainly my thumbnails. They are warped, as if I smashed both of them in a car door. They are warped- one goes up and down and up and down, the other goes up and down.

I gave six vials of blood last week and the tests showed my Vitamin B12 is HIGH.

I stopped taking one of the vitamins to avoid the increase in B12. Will that work?

I'm waiting for my pal, Dr. Lin to call me. Maybe she has something in her bag of tricks?

All I want is healthy nails- to match (what I thought) was a healthy body.
