You may be in a little flare right now and, therefore, your fatigue is even more debilitating The best thing that you can do is exactly what you are doing: take it easy, don't try to do more than your body tells you that you can do.
You've got a lot on your plate right now and you may be stressing a bit which will also exacerbate your fatigue and the fatigue can cause blurry vision. Again, try to get some rest and alleviate some stress.
I hope you feel better soon!
Peace and Blessings
Look For The Good and Praise It!
