I have to go soon and I won't be on the internet for a while so I just wanna say a quick word here before I go. I haven't detailed my LTC anywhere on BL so far, but perhaps some time soon I will if I get an opportunity. But I can give you guys some pointers and detail what I have learned from my experience.
My LTC started in August 2014 and the most hellish symptoms took 1.5 months+ to fade. After that I experienced several more months of slow recovery, but now at about the 6 month mark since my experience from hell, I consider myself fully recovered and I feel completely normal again. There is some very slight residual tinnitus but it doesn't bother me and my experience with a different type of tinnitus tells me it will fade as the years go by also.
I most definitely believe that if you've not been abusing MDMA hardcore for years (done it ~<50 times) then basically 100% of the suffering you are experiencing is purely a psychological phenomenon induced by the intense neurological experience that MDMA puts you through. Everyone who has an LTC that has done MDMA less than a dozen or so times, as far as I have ever seen, has a pre-disposed risk to anxiety and hypochondria and MDMA has set off a massive episode of this. You are learning, as did I, that MDMA has the power to trigger an intense anxious reaction in those who might be at risk of it, and deep anxiety is definitely one of the most hellish psychological experiences one can have.
The biggest hallmark of deep anxiety is it causing you to experience all types of mental, physical and emotional symptoms that you never suspected could be caused simply by episodes of anxiety, and thus you are not prepared for it either. Anxiety can manifest itself in almost literally any symptom you can imagine, and the best thing you can do is try to keep it off your mind as much as possible and give it time. You need time for your deep subconscious to heal into believing that the world is a safe place again. I've written another post up of tips to get you through an LTC so I urge you to have a look at the ways I got through mine.
I know that it's difficult not to obsess over your condition especially when it is intense and as long lasting as MDMA can cause, but at least if your anxiety keeps you resistant to the tips and explanations I and other LTC recoverers share, then at least I can be another voice of support and 100% honest reassurance from someone who has been through it that this will not last forever and your life will return to 100% normal in time, and that you can reduce that time somewhat by looking after yourself as best as you can manage.
Good luck guys! My thoughts are with you.
