Hey purple and flyingimam, I really feel you also. I have anxiety and worry about stupid things every day. I'll have a look at those papers to, I think I might have seen them before somewhere.

First time I smoked, didn't expect the high to be like it was but I was alone... felts like being in another dimension or outside of my body lol... it was quite scary but I wouldn't say that I panicked or anything.

Smoked several times for couple months after that without any problem, but then I started worrying about my heart condition which made me anxious while high. I have MVP and aorta regurgitation but only knew about the MVP then...

Few months later I started being cautious about getting "too high" but was totally fine with smoking small amounts without any problem. Then I got "too high" again and was really anxious, became afraid to smoke at all, but still wanted to. I was fine around weed and other people smoking it...

About... 10 (shit I didn't think it was that long) months ago I had a panic attack after vaporizing more then i expected, ended calling ambulance because my heart rate was at 200 and i was totally pale, trembling (which now I believe was a lot to do with low blood sugar)...

Couple months later, I slowly started getting paranoid that I would get weed in baked foods, had a panic attack sober for the first time and got depersonalization for 2 days, then I was paranoid about getting it in everything I ate and every time I ate i would be moderately anxious for 2-3 hours after until I was "certain there was nothing in it". Cant even stand near anyone smoking, can't smell weed without being anxious. I'm terrified to get high... from anything (alcohol included). Anytime I "feel weird" due to anything... lack of sleep, blood sugar, etc. I start getting anxious thinking I somehow got weed.

I've been like this for about 4-6 months as well as other things have started worrying me now I and I get anxious over things that never used to bother me.

The last month I have become much better. I've started changing my thoughts more rationally, eating healthier (but still not enough), taking some homeopathic remedies, doing some NLP, worrying less. I only get anxious a couple times a week (opposed to several times a day) I almost don't worry about getting drugs in food anymore, only sometimes, and worry less when I "feel weird" for w.e reason. But I'm still terrified to get high. Hopefully I won't fear it anymore because the herb used to help me with other things like eating before and I used to enjoy it. I know I'll be anxious free eventually.

I can't really say what has helped, but I know that changing the way you think about anxiety is a big thing. Basically you must accept it and stop fearing it/letting it bother you. Embrace the feelings. Like right now and today I feel sort "high" or just out of it, but I just think "oh well" because it's just a state of mind and feelings.
My recommendation is to look into homeopathic remedies, EFT, and NLP for anxiety/panic. I've found these videos to be quite helpful:
