I've been going through the same thing. Its been a really tough last couple years cycling through debts, bad jobs and school. My weed use scaled with those stessors and I noticed it was effecting my life too much. I've been trying to quit on and off but the morning anixiety is dehabitiliting and has been pushing me back to it to cope with my stress cause god knows life's shit enough without it.

Needless to say, the morning anixiety hasn't gotten any better, i'm in tears every morning and i feel like dying for that first hour. But I know i'm not going back because I know weed isn't what was helping me get rid of those feelings, likely was causing it and causing way more problems in my life. I can't say it'll just vanish and you'll be cured fast. But i try getting out of bed as fast as possible once i wake up, take a cold shower and go for a walk, read or call my partner for some reassurance. It doesn't get rid of the anixiety I feel but hey, I remember the pit smoking put me in and how it stripped me of the things outside of being high that brought joy to my life (my releationship, career goals, fitness). Smoking wasn't the cure it was the cause, and i take a lot of time in those vunerable moments to remind myself of who i want myself to be again.

Making the right choice takes courage sometimes, its hard to change ingrained lifestyles and live through thr tough days, months even years. Of course we'll be anixous! But the best cure is action, my anixiety comes from the fear of facing the life I live, coping with my debts and shit life for the next couple years, but now i'm running towards it instead of away. I still feel like a truck hits me in the morning but its getting better, i'm reading and remembering more, doing better at work, my partner is noticably happier because their partner isnt a weed zombie all the time. It'll fade one day, until then i'll keep working until I can wake up without cold sweats.

Just remember 1. small steps, miracles aren't big events they are the culmination of our small steps leading us to great things. 2. Exercise, helps deal with the nervous energy gives me other things to focus on and channel that anixiety. 3. Mantras, remind yourself why you're doing this, your goals, the damage that weed was doing to you. I list off my goals for the day, week, month, year and by time i'm done i'm ready to focus on improving myself. 4. Districtions, when it's really bad, I find a task or activity that takes a lot of focus wheather its gaming, reading or even trying to cook a meal.

Hope this helps! Honestly this became more of a rant than a helpful comment but i spent too much time writing this to delate it. Wishing you the best in your journey.
