I was at work today absolutely fine for 90% of the day and then right at the end I bent down to help out a customer and found I felt suddenly lightheaded and just a bit horrible, this then made me worried and I had a bit of a panic attack over it, should I be concerned about this as I’ve been having a few headaches the last few days and thinking my right eye feels weird or is this anxiety doing it’s best again alongside just a bit of blood rush from bending down or low blood sugar ?
