Is there anything in particular in your life that is bothering you, or are you just feeling down for no reason?
In either case, I would stop using Mdma for a long while, or perhaps forever. That's a crazy amount of Mdma to be using; I was abusing it for 4 months, even using it 4 days in a row once. You honestly might get worse if you quit, problems can remain, or even appear, long after you stop using and the brain begins to rewire itself. You might be completely fucking yourself up long term. Stop rolling it's incredibly harmful and you probably have brain damage from it. Think of this wonderful and sensitive biological system you inhabit, the brain of which is the epicenter. You are putting a chemical in your body that literally kills off a very important part of the brain having to do with high level emotions, week after week. How long has this been going on?
I really hope that you arn't rolling this weekend.
