(((PFM)))

I can really relate to the problems that you're having as this is a daily occurance for me. In my case, the cause is my brain unable to work more quickly, at optimum speed. This is due to brain surgery (removing part of the left hippocampus) as well as TBI, affecting the left side of my brain 1 year later.

I have been advised, however, that depression is known to cause some similar symptoms that I struggle with ~ such as difficulty processing info, recall, feeling overwhelmed, anger and frustration.

I would recommend that you see a doc about these prob's, and see if a fix can be found to relieve some of this stress and discomfort for you. Very best wishes!
