You've been on BL long enough to come across info on MDMA and spacing but: the
minimum wait time between sessions is thought to be 30 days, some theories suggest up to 90 days. If you're at 62x, you're roughly at 3x the suggested minimum amount- 2 months is likely not enough time off.
For those in your predicament, taking an extended break is usually the best course of action. During that break, it's best to avoid replacing MDMA with another drug that interferes with serotonin or it's levels (avoid bk-MDMA, mephedrone, and 2c chemicals). Piracetam is extremely helpful to those who have damaged their receptors (and even those who haven't), you'll find quite a few threads on the topic in here. I personally found it instrumental in recapturing the "magic" that MDMA had when it was newer to me.
If you want to check out a thread on spacing and read others experiences:

Over a year ago, I stumbled across this report on erowid on the effects of piracetam and shared it on here - many of those who read it and tried it have had excellent results:

I don't think that you'll never be able to use MDMA again in your life time- I think you need an extended break (6 months to a year), and the best way to get through that break is to not allow rolling to be in the forefront of your mind. Accept that it's not a part of your life right now, and move forward. For some who have abused MDMA, no amount of break seems to return them to the mind-blowing meaningful MDMA experiences they once had- for others, an extended break does just the trick. It's impossible to say how it will go for you, but so long as you give yourself an extended break, you'll at least get a chance to recover as much as is possible for you.
