What Causes Anxiety And Blurred Vision In A Heart Patient?

I am 58 years old, and have COPD (1 yr), stroke CVA (nov 2013) with no residuals so it s been said, hypertension for over 25 years, and past uterine cancer in 2012, stage 1, with no chemotherapy. Ever since my stroke, from time to time I will feel funny in my head, it doesn t happen all the time, but I have been told it could be anxiety. Anxiolytics do not agree with me, so I had to stop which took a long time to get out of my system. I am overweight about 70 pounds and know I need to lose some weight and wondering if maybe this is why I don t feel good sometimes. The systems I get is unsteadiness, like feeling of falling down especially if going into a large store like walmart, bright lighted areas, crowds, noise, sometimes trembling. I type on a computer for a living at home (medical transcription), and sometimes my eyes have a had time focusing, sometimes for a couple of hours. Im not sure if my problem is due to maybe my BP meds need to be adjusted, anxiety or maybe I do have a residual effect from my stroke. I have seen my PCP about this and my neurologist with no solutions to my problem. My PCP states that I m special.
