Anxiety Disorder or PAWS? 5 months off weed

Please hear out my story, any advice or if anyone experienced anything similar would be great to know.

The few weeks before I quit, I started getting leg pains/ tingles everytime I smoked, that feeling even lingered when I was sober. One night I was smoking and the pain/tingle really intensified to the point that I passed out and followed by convulsions which according to my friends it really looked like a seizure. I quit cold turkey after that for 10 days. I had really bad headache, insane anxiety and was sleeping a lot. (Doesnt look like typical acute withdrawal phase right?). I smoked again and had a similar reaction, but this time it really freaked me out, I felt dissociated, everything around me looked distorted, colours and lights were dimmer, it felt like I watched the world from a POV movie. I didnt touch weed again and it's been 5 months now.

From what I've read, those leg pains that I had were apparently warning signs of anxiety, and that 'seizure' and dissociation event was due to the anxiety tipping over board. Can someone confirm that?

Since I last smoked I've been struggling with literally all the symptoms of anxiety: tinnitus, head pressure/headaches, chest pains, tinglings in limbs, hot skin, eye floaters.. and the worst indigestion. I literally could not eat anything nor digest it, had really bad constipation and bowel problems in general.

Month 3 into quitting, I went on lexapro 10 mg and I'm much better now. Anxiety is still here (head pressure and headaches, floaters..) but somewhat under control. Indigestion and bowel problems were 100% due to anxiety as they are nearly dissipated since I've been on medication. So it's been 2 months since I'm on medication, 5 months since I quit weed.

I know it's a very long post and i appreciate it if you made it til here. Am I experiencing PAWS or did I trigger a latent anxiety disorder from weed?
