Hi CrazyRG.

Hormonal imbalance/deficit and autoimmune issues can have an insidious effect on our cognitive skills and executive functioning. Losing the ability to spontaneously function of course brings with it great worry and depression. These deficits I mentioned may be nothing...but they may also be everything. Having a full blood and hormonal screening would be a very good place to start in my opinion.....Ruling out things that can be readily addressed, so as to move forward toward pinpointing what's really going on.

Find an integrative doctor who is invested in dealing with symptoms rather than text book diagnosis'. Be your own advocate, and if they dismiss your concerns as ageing or a depressive phase....get vocal. I am in no way undermining how serious and utterly debilitating depression can be, but depression is quite often a symptom of an underlying problem that needs addressing.
