Went to the grocery store today. As I was walking around, I started to feel weird. The best way to describe it in words is almost like trying to black out but still awake. It's like when it happens, I try to shake it off and it goes away for a moment, then happens again. At one point I almost fell down. So I hurried up to get out of there. (I can't drive due to vision, so my grandmother takes me). I felt dizzy and almost trying to black out but it doesn't completely go because I shake it off by shaking my head and refocusing. Does anyone understand/been through this before?
