I Woke Up Earlier At About 8pm After Finishing My

I woke up earlier at about 8pm after finishing my nightshift at 7am. I woke up feeling very shaky and sick. I have currently been sick 3 times. I'm worried it could be hypoglycaemia as my eating habits have been very off the last week. I'm also worried it could be a anemia as My iron intake is very low as I don't eat much red meat :( I just don't k ow how to stop the shaking and sickness it's really horrible
