Hi,
I was looking for the relationship of low Vitamin D and mental illness. I found these articles:
Is this D vitamin to worry about? Vitamin D insufficiency in an inpatient sample

Quote:
Conclusion: Low levels of serum 25-OHD were found in this patient population.
These data add to the literature suggesting an association between vitamin D insufficiency and psychiatric illness, and suggest that routine monitoring of vitamin D levels may be of benefit given the high yield of clinically relevant findings.

Hence, the diagnoses that have been hypothetically linked to developmental (prenatal) vitamin D deficiency, schizophrenia and autism, had the lowest 25-OHD levels in this adult sample, supporting the notion that vitamin D deficiency may not only be a predisposing developmental factor but also relate to the adult patients’ psychiatric state. This is further supported by the considerable psychiatric improvement that coincided with vitamin D treatment in some of the patients whose deficiency was treated.

Additionally, a relationship between vitamin D deficiency and anxio-depressive disorders is likely since low serum 25(OH)D concentrations are closely associated with active mood disorders [70] and have been proposed as the missing link between seasonal changes in photoperiod and sea- sonal mood swings [70].
In line with this, one clinical trial supported the efficacy of vitamin D supplementation on mood disorders [108].
Finally, accounting for depression is of primary importance while exploring the involvement of vitamin D-related cognitive functioning in locomotor function as depressed people are usually less active and loose muscle mass as well as sensorimo- tor performance [70].

Researchers have not focused much on anxiety:
I found one promising reference on Anxiety that I do not have access too via Google Scholar.

I was out side today for almost an hour from 3:00-4:00 on a cloudy day. Later I felt less anxious than I normally do.
I will try to go out earlier in the day around noon (HA!) on Tuesday.
