I feel the same way , some times I think about matters stressful or not I find my self to stop breathing or if I am hungry it much worse , also I can be in and around people’s feeling stress just being around people’s wondering when some one will come out with a gun and just start shooting peoples , also straining to try to see small print on my phone some times can make me loose vision in one or the other eye for a few minutes , also I can not pay any video games because I start concentrating too hard on how to beat the game and I forget to breathe and I start feeling light headed , also when working I am trying to be careful thinking about my work and safety I will forget to breathe and my wife said I start turning blue , the best way to help me stop feeling light headed when I am breathing is to drink gatorade, mixed with the powder with rich mixing .
And to avoid thinking about thins to much and stay away from crowd of people’s I do not know , I had to MRI scans with the dye they do not see any arteries that’s clogged with plaque and I’ve had two exams and they say nothing wrong with my eyes.
The only think left is to have me put on a heart monitor to see if I am trying to relax to much I am slowing my heart beat down to much and making me have dizzy spells . I am 57 years old male
