Hi Michele!
Congratulations on making the best decision of your life. Yes, we have a surprising amount of lady quitters here. And actually, a surprising amount of EMTs, too. Really, we have people from all walks of life here, which is awesome.
It sounds to me like you've truly had enough with the tobacco and nicotine nonsense. This is great news, because it takes a sincere hatred for that poison to quit. All I can tell you is that early on it can be a bumpy ride. You might be short with people, or irritable, or shaky, or foggy, or any number of things. But the important thing to understand and bear in mind is that none of these withdrawal symptoms are permanent, none of them will kill you, and none of them are things you can't overcome with willpower, the accountability you'll find on this site, and a strategy going into it. Don't forget that this is something you are capable of doing. It is entirely possible to enjoy life and all the activities you used to do without nicotine, but it's gonna take you powering through the temporary, yet annoying withdrawal symptoms.
Make sure you have some sugarfree gum, or candy, or sunflower seeds, or whatever else you find helps with the oral fixation part of this thing. I know you mentioned you used snus, and a company called Smokey Mountain makes a tobacco and nicotine-free pouch product you could order online if you think that'd be helpful to you. Otherwise, exercising (even just walking), drinking lots of water, and getting rest whenever you can is going to help you tremendously.
Welcome aboard, and I'm glad to be quit alongside you today!
