Hey Sweetie,
You'll see when you get your new Claire Weekes book that she mentions vision disturbance as a symptom of "Nervous Fatigue." My head has been utterly, utterly foggy the past couple weeks, and my vision has not been good, Snowy - I can barely read!
You know when we frighten ourselves, it just intensifies everything! As hard as it is, try to remain very calm... you can call your doc on Monday if this continues, but maybe it will be gone in the morning...
These days I'm refusing to let anything weird that my head or body do phase me!

Just bumbling around doing whatever is possible, then saying F*** IT...
(((HUGS))) and try not to be afraid...
JJ
