What are withdrawal symptoms from benzodiazepines?

Hi doctor,

I have been taking 10 mg of Diazepam daily for about five years. I am taking Amitriptyline 100 mg, Dexamphetamine 10 mg, Propanolol 120 mg, Buspiron 30 mg, Imovane 15 mg and Diaz 10 mg. I ran out of my prescription three days ago, and I think I am having Benzo withdrawals. I am very nauseous and anxious; my mood fluctuates from minute to minute. My muscles are sore, I did not sleep last night, I have no appetite, and my hands and feet feel numb and cold. About half an hour ago, I started to feel weird, then my right arm seemed to be jerking weirdly, and I was not sure if I was purposefully doing it, same for some odd noises I was making. It seemed involuntary, but I was just so confused. I am worried I had some minor seizures. But maybe I am overthinking it. I feel much clearer now than half an hour ago, but I am weak, exhausted, and confused. Please help.
