So, about 3 months ago, I took one pill of ecstasy. I was really nervous going into it, as I had heard horror stories. As soon as it kicked in, I had the worst panic attack of my life. I really thought I was going to die some how, and I couldn't even stand up because I was so lightheaded and faint. That lasted for about 20 minutes, then I felt great. For the next couple of weeks, I had panic attacks, and actually went to the ER and explained it to the doctor. He said that it probably would go away, but it's been a while. I have smoked marijuana about 10 times since the ER visit (I know, stupid, right?) which is probably slowing the healing process. I also tried psilocybin mushrooms about a month ago, and had ANOTHER horrible panic attack. I think that REALLY slowed down the healing process. All of the panic/anxiety attacks besides the two caused by drugs aren't nearly as bad, but it is scary. They usually consist of an increased heart rate, and a general feeling of uneasiness and nervousness. Those ones are the anxiety attacks. The horrible ones are the panic attacks, because they involve hypochondria. I've convinced myself of a heart attack, brain tumor, brain aneurysm, stroke, and, now, heart arrhythmia. I can deal with the anxiety, but the hypochondria is unbearable. I can't accept death. Anyway, my general question is, will this go away? I read somewhere that anxiety caused by MDMA can take up to a year to go away. It takes your body that long to re-balance the lost serotonin and all that. I also get bursts of euphoria for some reason, although they don't last long at all. I'm 16 years old now. Thanks!
