Major anxiety after quitting Zyn

Hello 30 (F) here, I recently stopped using nicotine after a decade of using. I started with cigarettes, the vaping and then nicotine pouches. I quit cold turkey three weeks ago. I now have an increased sense of anxiety. I used to be a worried before and noticed my negative thoughts would increase when I just pop a Nico pouch.

Now off Nico pouches I've noticed a huge increase in anxiety, negative thoughts. Having a fear of going crazy, being really sensitive to anything loud and social anxiety. Obsessive thoughts and intrusive. I can manage them well and nothing harmful to myself or others at all. I never had this issue before. Honestly, it's kinda scary rn I don't want to be like this forever or for it to get worse.

Right now, I'm still functioning like normal but I am struggling with things I was okay with before. I recently, come from holiday after consuming large pints of alcohol so that didn't help with my anxiety.

I've got some ashawgha and CBD drops. Which helped a little but if I go into a situation which causes me a little fear it will amplify it.

Please anyone who has quit Zyn or any nicotine please let me know how long this lasted. I am thinking of talking to my doctor.

I'm now three weeks moving into my fourth. I have quit drinking now to help. But I hate feeling like this. It's like my anxiety has peaked week three. Maybe it's the alcohol I consumed on my trip.

Please let me know what people have done to reduce this.
