My situation is similar but is manifesting in different ways.  I was always the "party girl," active social life, active church and community life, public speaker, getting promotions at work, etc.  Now I have social anxiety, panic attacks, brain fog...and anger issues.  I was NEVER like this.  Two years ago I had brain scans which showed mild white matter disease and left and right parietal lobe atrophy.  My symptoms were very different when the scan was ordered (dizziness, memory issues and vision issues) But I suspect my current issues may be related.  My point is...consult with your doctor and hopefully they will order a brain scan just to be sure all is well there.  I am totally scaring myself with these anger problems (explosive) and think I will return to my family doctor to ask his opinion on this maybe being related to my brain issues.  Thinking of you and hoping/praying you get some answers. BTW....Prozac helped me a lot with anxiety a few years ago but my husband didn't like me being on it so I went off.  🙄  Maybe it would help me again.  I feel broke, too.  Utterly broke.
