I never did as much MDMA as you, but I still had a difficult recovery process from years of doing it. What I'm about to say comes from DIRECT EXPERIENCE and not reading articles or other people's stories.
First thing's first... avoid all MDMA for 6 months, but up to 1 year is ideal. Your serotonin system has taken a heavy hit. Also note that in the future if you do MDMA again, you should only do it once every couple of months MAX and at lower levels. The healing work you need to do to rebuild your receptors means they will be fragile in the beginning, and even minor abuse can trigger a relapse.
My regimen was:
- healthy diet --> increasing veggies and whole grains a lot, less meat (but not cutting it out), no fast food; the veggies I consumed daily were kale, broccoli, carrot, beet, a bit of fresh onion, a bit of fresh garlic, a bit of fresh ginger, sprouts (all kinds), sprouted beats, pumpkin seeds; for dressing I did olive oil, apple cider vinegar, lemon; but the more veggies you can eat the better, their polyphenols will give you all the building blocks you need
- exercise --> for me I found weight training worked better but do whatever feels best; note that "going for a walk" is not enough, you need to run, swim, weightlift, or do something moderate to vigorous
After you've started the first part, start taking nootropics daily. I did rhodiola, hydergine, selegiline, piracetam, vinpocetine, choline. Take a single dose of each, together, in the morning with a high fat meal (like fried eggs, meat, or just take them with fish oil -- helps them absorb better). Because they potentiate each other, I don't feel additional doses are necessary beyond this one daily dose. Your problem is long-term and chronic so it needs a lower dose over a longer time. The effect will be cumulative and will increase over time. Hydergine and Selegiline are rx only in the U.S. but because there is evidence that they can cure depression (not just treat it), you may be able to convince your doctor to give you one. If not, shop online.
You can add 5-htp or tryptophan to this combo, but IME it's not necessary.
You need to be on the nootropics for at least 60 days, so obtain enough for this purpose. And of course, avoid MDMA because if you continue down this road you will ruin your life.
Any questions, just ask.
