welcome to a very active support network.
i am not sure about the blured vision........ but the mood swings.
yes it is common.
what i know about myself... and a few friends here i have spoken to.........
our ability to control our emotions becomes decreased.
actually our emotions are also decreased.
all we have left is the extremes.
extreme happiness or extreme anger.
our emotions switch on and off without us being able to control them properly.
we spend most of our life without any emotions.
this is just me and a couple of friends.......
but it may help you understand what is happenning to you.
When you're stressed, You eat Ice cream, Cake, Chocolate & Sweets. Why? Because stressed spelled backwards is DESSERTS.
