I've been dealing with literal vision problems and pretty bad brain fog for months.  Months.  I've been hiding some pretty major things from friends and family during this time.  I won't go into details, but let's basically say that I came clean yesterday.  Had a major cry with the wife.  I felt so much better afterward.  Today, my physical, or what seemed like physical problems were *way* more mild.

I thought I was literally injured due to substance abuse.  Maybe it was anxiety all along.
