Im 26. Ive been tested for diabetes and that came back negative - but every day at some point, my hands and my arms shake, I feel weak and as though the blood rushes from my body, I tend to suffer with panic attacks which I am starting to learn to control, so when I start to shake, as long as I keep calm and take deep breathes I manage to get myself something sweet to eat or drink e.g. ice cream or cola then after a couple of minutes I stop shaking? - if I can't get to anything I have to go and lie down and then it ends up in a panic attack and I'm in a right state if I'm honest, what does this mean?
