Okay, the first thing you'll want to do is relax. You don't want to get too worked up if you're already experiencing these symptoms. Next, know that it will go away. I promise. The reason you are feeling this way is because when you take MDMA, regardless of how far apart, you are going to be using up a lot of serotonin very quickly. That's what give you that happy feeling. Serotonin helps regulate things like stress, anxiety, depression, etc. When you run out, you have little left in your brain to combat these things. Now, when combined with Adderall... you're really pushing your mind to the limits. In fact, when you take an amphetamine with MDMA, it can result in the thinning of your cerebral cortex; the part of your brain that makes you, you.
Amphetamines also have a similar effect on your happiness/anxiety levels when you come down. I used to get a massive amount of anxiety when I would come down from Adderall. It usually ended with me in tears for no reason. This is because of the immense emotional strain you are putting on your brain. The most important thing to remember is: the comedown of these drugs will affect each person differently. While you experience anxiety coming down from MDMA, some experience the opposite. You need to listen to your body and learn what it can and can't take.
Now we need to take a look at how you rolled three times in one month... that is a serious no-no when it comes to MDMA. Your serotonin levels will not return to normal for about 90 days after you consume MDMA. So you just put a huge limit on how much serotonin your brain has, resulting in severe anxiety. This will go away, however, considering you let your brain recover for 90 days before taking anything else, even if it isn't MDMA or adderall.
I am currently recovering from psychosis due to MDMA. It was one of the worst experiences of my life. I depleted my serotonin and dopamine levels to the point of no return... not for a very long time anyway. My life felt like it was a living nightmare, literally. Everything felt like a dream, as though nothing was for certain and nothing was entirely real. It even got to the point where I was actually batshit crazy... running around my apartment screaming at demons in the walls. It's not worth it, trust me. But please don't let that scare you... you don't have psychosis and you probably aren't going to get it if you start taking care of your brain. So here's what you can do to help your brain through this stressful lack of serotonin:
1. Don't let your anxiety get the best of you. I know this is much easier said than done, but if you really keep track of your anxiety and what sets you off, it could really help you get past the anxiety altogether. What I mean by this is: when you start to get anxiety, as yourself why? Question it. Don't just let it be there without reason, or it'll consume you. If you ask yourself why you're panicking... the thought processes that follow often help you to rationalize the whole situation and melts the anxiety away. Take control of your brain!
2. Supplements. One of the best supplements you could be taking right now is 5-HTP. Our bodies turn 5-HTP into 5-HT, which is serotonin. So by taking 5-HTP supplements, you're directly helping your body combat the lack of serotonin. There are also many other supplements you can take to help yourself through the MDMA/amphetamine comedown. Just do a little googling. You can even purchase something called a "Rave Box" for $15 online that sends you all the supplements you'll need before, after, and during a roll... all in one box! It's very affordable and your body will thank you.
3. Stop taking drugs. All of them. Your mind needs to rest and naturally recover. Serotonin isn't the only thing your brain is lacking right now, and almost any drug can prevent you from recovering. In some cases, marijuana can ease some of the side effects of a MDMA/amphetamine comedown because it helps your body get back into balance, and can lift your spirits up. However, be warned. I used to smoke marijuana every day of my life until I started doing MDMA. Following my consistent use of this drug, I noticed I was no longer able to smoke marijuana without getting severe anxiety or even having an anxiety attack. So like I said before, drugs effect everyone differently and you should keep that in mind.
So to sum things up, you're going to be okay. I strongly suggest ordering some supplements for yourself to help you recover a little faster. Other than that, just take it day by day. It'll go away eventually, you just have to know how to help your brain out in the process. Please, just stay away from drugs if you want to get better.
