Yeah LSD can't be reliably tested for...
I guess I'm wrong but it just seems so odd...I knew a chick who was allergic to it and she said she didn't have reactions to it just allergy symptoms, but I heard about some kid getting psychotic around magic marker fumes too. I hope you find peace with this. I am pretty sure that this disorder would be treated with anti-psychotic drugs rather than therapy so I'd be careful about this. They have horrible side effects and can cause permanent damage resulting in tardive dyskenisia, (sp?) that is a disorder where body movements can become twitchy and uncontrollable. You are smart enough to probably be aware of that, however. Good luck!
