Hey @Walker ... you are not alone, and you are most definately not abnormal for this reaction.
Nicotine addiction cause the nicotine receptors in our brains it pushing any button they can to get fed, ergo a hit. Remember, when you were a smokers, if you hot stressed and had a smoke the stress eased? Yeah well here's a news flash to help you stray quit....it wasn't the nicotine easing your stress, it was the nicotine receptors amplifying it...bad thing happens, your brain stresses, the nicotine receptors go 'ooh we ain't had a hit for a while, lets just turn th ius up to 11', you have a smoke, nico receptors turn off, stress level drops....and you think, ahh the smoke made it better...yeah nah it just turned of the nicotine receptors which amplifying and exploiting you. For 30 years you have conditioned yourself that smoking eases the stress, the nicotine receptors in your brain are starting to realise you are serious about this quit business and are amping everything that has worked in the past to 111 to try and get a hit.
So, during the first month particularly you need to keep you fluids up and you need to keep your blood sugar levels managed. Drink lots of juice, eat some fruit, suck on a hard lolly. This really helps with craves.
I'm not trying to minimise your experience, I remember clearly think i was having a heart attack during my quit and it b eeing a panic attack. Its scary shit.
Another helpful thing is to have a placebo, when you start to feel anxious, stick a hard lolly (candy, sweet) in ya mouth and suck on it. Still, nearly 3 years later, if i get stressed i will grab a chewie (gum, and no not nrt) and the act of chewing is calming and centering. I'm not doing this avoid going f our a smoke, don't even consider that, but because I reprogrammed my brain that chewing gum eased stress.
Your nicotine receptors will exploit anything and everything to get a hit. But it gets easier every day. You just have to hang in and let your brain unlearn 30 years of programming. 10 days is sensational.
