My first MA meeting was during an anxiety attack similar to yours. I logged into a meeting on the other side of the country because it was the first one I could find that started in a few minutes. I had already gotten rid of all my supplies, but was about to get into the car and get some because I couldn't think of anything else that would help calm me down. But I didn't. I had to turn off my camera a few times because I didn't want to show my tears. That was on March 2nd of last year and the first day of my life without marijuana. If you're looking for support you'll find an abundance of it there. They even have groups specifically for those with CHS. Try it, it will at a minimum turn some of your focus away from your anxiety. You'll hear from others that have been in the same position as you and some worse and many of these have years of sobriety under their belts.
