I know how u feel. I also get the light headed, slightly dizzy, disorientated feeling with pins and needles and a hot rush of adrenaline all over and no matter how much I tell myself it's just anxiety it never seems to work. I'm feeling exhausted even though I got enough sleep last night but I have had heightened anxiety for the past few days so it's probably that. Just hang in there, I know exactly what you are going through. Some days are better then others but we just have to push through because it will definitely get better.
