Are you on any Anxiety Medications? I know I am doing that as I type, But it's from Missing one Anxiety Pill...Kinda like a Head Zap..Some people call it Head Shock.lol.. And the concentration is the worst with me also...
Suggestion. Have your thyroid checked. I have had what you are describing with thyroid disease. It can very definitely mess up vision, memory, and the way your head feels. Simple blood test will tell if that's the problem or not. Best wishes to you.
Thanks for the reply. Im not on an Anxiety medication.. but maybe this is the problem
Thanks for the reply, Ive had blood tests and everything was fine.. but I shall look into this further
