I used concentrates for about a year and a half, every day, during day and night.
For me, I was pretty sure it was caused by weed. Because the problems all got a LOT worse the day after I quit. I had many symptoms when I was smoking regularly too, but they were mild; 2/10. Right after I quit, they went crazy - 11/10. Then, there were a couple times I thought I was better enough to start smoking again, and I did. Concentrates again, for a few days. After those few days, the headache/anxiety/insomnia all came rushing back like it was day 1 again. So I am certain this is from weed.
I tried a lot of things - eating and sleeping healthy, exercise, drinking lots of water, suppliments; even tried loading my body up with calories and sugar; nothing worked except time. In my experience it doesnt even matter what you think or if you are paranoid about it, your brain is re-acclimating on its own subconsciously.
Thats not to say that obsession is a good thing. It certainly prevents you from doing other things like work or study. Another thing to keep in mind is that anxiety/worry is a symptom of paws (for me at least) - I would worry a lot about something that wouldnt normally worry me. Keep that in mind whenever you feel anxious about something.
It took a long time for me to get in that groove, but I eventually accepted that this (shitty) life is how it is for the time being, so I had to roll with it. It was/is a part of my life for the time being. Time heals though, in this case.
Do you feel any better now than you did on day 1?
