Can headaches, vision problems, brain fog, and fluctuations in blood pressure be signs of anxiety?

Hello doctor,

I have had anxiety probably my whole life. Lately, it has been getting worse though. I am not sure if all my symptoms are connected to anxiety. I cannot eat anything sweet in the morning because I feel light-headed, my heart racing, sweating, and might lose my vision for a few seconds (my sugar levels have always been fine). Multiple doctors did blood work, I was referred to a cardiologist too after my PCP realized my blood pressure jumps a lot when switching positions from lying down to sitting to standing up, otherwise blood pressure is fine. My heart is fine. I started having vision issues about eight to nine months ago. I have worn glasses since I was 14, so it is not that my vision is worsening. Two times I had fuzzy spots in my vision and a headache, and for about 30 minutes my vision got blurry to the point where I could not even write a text. Urgent care told me it might be a migraine. A few months later the same thing happened again, so I lied down but I did not feel better. So after an hour, I got up and then started to feel numbness in my hands and face, and ringing in my ears. I went to an ER and did a brain scan. I was told everything is fine and it is just anxiety. When I walk for more than a few minutes my vision is always bouncy like I am skipping. My biggest issue is having brain fog and not feeling 100 % present and aware. At times I catch myself “coming back” when I am mid-sentence. I have never taken any drugs in my life, but it feels like I am on some drugs. I do not feel sober. When I am concentrating on something like writing or reading, I am fine, but when I am walking around and talking to people I just feel weird. I think I have always had anxiety, but this weird feeling and being sensitive to sugar in the morning started only when I was about 18 and I am 23 now. I guess it is somewhat like an out-of-body experience that many people feel after some traumatic event, but I have not had anything traumatic that has happened to me. I need help. I am trying to finish my bachelor's and raise two kids. But all my symptoms have had a huge impact on my life. I have health insurance and the doctors I see are pretty dismissive and want to prescribe something as soon as I walk in the door. Please, help me understand if all these symptoms could be from anxiety and if is there anything I could do about it. I do not think I have ever had a panic attack nor do I freak out. Of course, at times I feel nervous, but like I said my biggest issue is that I am not feeling sober and present.
