Hey Scooter, welcome to KTC! By quitting you have made one of the best decisions of your life. In time you will find your only regret will be having not done it sooner. It is not a picnic, but not as tough as your brain is trying to make it out to be. For now just focus on quitting one day at a time. Just make it to the end of a day. Tomorrow (when it gets here, we don't think about tomorrow here at KTC) repeat the process.
Trust everyone here when we say it will get easier in time. Much easier. Fabulous, in fact. But the only way it gets easy is to stop putting nicotine into your body and letting the body heal, the brain rewire. You - like me, like all of us here - are a nicotine addict - and there is nothing we can do to undo that. But you never have to feel this day 1, 2, 3 day crap feeling again as long as you stay true to your quit.
Go over to August 2021 and post your name, day count and promise. Right now there are four guys going through EXACTLY what you are going through now.
