Abused MDMA, need help.

Winter and Spring 2024: 2-4 pills each time usually weekly sometimes biweekly. Summer 2024: 5-8 pills each time multiple times a week or biweekly till August 18, one time in this period I managed to take 20 pills in one night (I know. I don’t understand how natural selection didn’t take me.)

I have quit since August 18 as I felt barely anything after taking 11 pills. I really do enjoy MDMA, and I would like to continue it (only 1 pill max and 3 month rule) because it made concerts and festivals so much more enjoyable (Im autistic and love but hate social situations). I never had any issues with serotonin or anything other than headaches on my comedowns and sleep issues the day I used and the day after. Also, yes, the pills were tested and were mostly pure (street pills will always have a bit of mash in).

I know what I did was incredibly stupid, I’m a social MDMA user and my friend group were constantly inviting me to seshes, I got out that group now.

How much longer till my serotonin receptors, tolerance and serotonin levels go back to normal (so I can get the effects again)?
