It sounds like you're going through a tough time, and quitting smoking can definitely be challenging. One approach that might help is transitioning to vaping. Many people find it easier to quit smoking by switching to e-cigarettes first, as it helps to reduce nicotine cravings while still giving you a similar experience to smoking.
Vaping is generally considered safer than smoking because it doesn't involve burning tobacco, which releases harmful chemicals like tar and carbon monoxide. Instead, e-cigarettes vaporize a liquid containing nicotine and other ingredients, which is less damaging to your lungs and overall health. I found a site with
Pure Mist 10ml E-Liquid & Vape Juice, which might be a good option to start with. They offer various flavors and nicotine levels, so you can find something that works for you as you work on quitting smoking for good.
