Can't really address the anxiety issues.

But experimenting on myself and then some friends following what I did... has led to noticeable improvement with mild depression and memory loss as the result of prescribed medication...

The following supplements have helped with mild depression:
Fish Oil
Vitamin D3
B Complex

This helped with Energy
B 12 ( Methyl type/chewable)

This helped with memory
PS 100 ( check reviews on iherb)


Mood swings are tricky and can be aggravated by ADD meds. You likely need an evaluation.

Of course you should double check with a medical professional any and all supplements you decide to take.
