Welcome.
The only stress that nicotine relieves is the stress of not having your nicotine levels high enough.
Face the withdrawals head on. Freedom lies at the other end.
Post roll every day. Post roll as early in the morning as you can, before you leave the house.
Remember that posting roll is a promise to this community, every one of us. Keep your word. Stay quit.
I'm not a psychologist, but I'd bet your anxiety will improve after you've been quit for a while.
