No Lunulas at all and slow growing nails + mental issues. connection?

[Omiod]

Hello,
It never occurred to me that i'm the only person in my whole big family (including my very sick uncle) who has absolutely NO lunulas what so ever. I also paid attention everywhere. Docs waiting room. shops. Everyone's got their lunulas (or in some cases nail polish ;)
On the other hand, I'm the only one in the family who is a complete nutjob. I have bad memory, I'm irrational; I lack logic, I'm basically a mental wreck. I've been diagnosed with schizophrenia while i'm clearly not schizophrenic and my current doc also admits that and is pushing me to go off meds.
I read somewhere that lack of certain nutritions may cause absent Lunulas. Possibly due to malabsorption.
Am I (and my brain) just starving somehow? or am I just a nutjob with benign nail issues?
