I've been like this for so long and for some reason, especially in the last weeks. I barely slept before but now I'm up literally all night and maybe doze or nap from mid-morning until afternoon. That's it. But I can't handle waking up in the mornings anymore. I wake up nauseous, sweating, shaking and jittery, palpitations, stomach cramping and like someone above mentioned, feeling that HORRIBLE wave (after wave after wave) of dread and fear. I have a lot of physical health problems and every time I wake up my body is (already) in hyper-vigilant mode and terror about what the day holds in terms of pain, symptoms, etc. By 7 or 8 p.m. while I still feel anxious, the hugely overwhelming anxiety has settled a bit...until the next morning when this neverending nightmare Groundhog Day repeats once again.
