I'm in the middle of a protracted mental health crisis, basically nonfunctional professionally and barely able to keep my personal life together. My psychiatrist changed around my meds and increased my antidepressants, but my anxiety and sleep has gotten way worse, and my usual difficulty of getting side tracked and not staying on task has been on overdrive.  My wife got concerned enough that she talked to my psychiatrist and now we're starting Lithium. 

I feel like absolute shit, and I can't keep myself from doing these fucking little tasks, even though my life is literally falling apart around me.  Is this normal?
