This is for anyone strugglng after an mdma binge.
I used mdma for 12 years in the San Francisco and New York party scenes. I have a lot of experience with what you're describing. Here's what helped me get through what felt a lot like depressive disorder:
I am incredibly sensitive, in all ways, so the phenomenon of not being able to harness my emotions, particularly positive ones, was very traumatic for me. As folks have suggested, CBT worked wonders for me in terms of learning how to balance emotions. But sometimes I didn't even feel as though I had emotions to balance out. I just felt empty. When I felt this way, meditation became my saving grace. It allowed me to ignore everything around me, and focus on my breath and myself. As I learned to be more in touch with my own thought process, I was able to access positive and negative thoughts, and therefore, those feelings as well.
Secondly, I focused on my physical self. I began to understand just how important it was for my body to be "well" in order for my mind to follow suit. So here's what I still do for myself, for all around wellness:
Drink plenty of fluids. This seems obvious, but often we forget how vital water is to our health. Most of our body is made up of water, and a whole lot of it gets depleted when we roll. Try for 2 liters a day, for a few days. I substituted coconut water which also has great electrolytes in it as well.
Take a multivitamin. Again, just giving the body back what got depleted.
Eat whole, fresh foods. Raw fruits and vegetables are more nutritious than cooked foods, as heat sucks all of the stuff you need out of the plant or vegetable. So go for salads for to easily accomplish this one. As many leafy greens as you can handle, but all veggies and fruits, especially those that are purple, are going to be great for giving re-arming your body.
Do some gentle stretching or yoga: Our muscles ache after a night of mdma use, and paradoxically the only way we can feel better is to keep gently moving. Movement gets the blood flowing, which allows all of the nutrients you are putting back into your body get there as quickly as possible.
If you can, get in a hot tub or sauna. Or just take extra hot baths. Sweat those toxins out.
Be gentle with yourself. When you can, rest. Watch movies, read books if your head doesn't hurt to badly
and be kind to your body and your mind. Watch comedies, have sex, hang out with friends who will lift your mood. Get those natural endorphins flowing.
Most of the tips I gave you seem like physical solutions. But body pain can be a reflection of our mood. Certain types of pain is psychosomatic, meaning it is dependent on the state of mind you are in. It also can work the other way--if you are good to your body, your temperment is going to reflect that. Remember, your mind is powerful, and the mind-body connection is stronger than we realize sometimes. If you can muster the strength to meditate and think positively, along with healing your body physically, things will change quickly.
Try all of the above for a few days. I promise you will at least feel slightly better. I suggest trying everything I've outlined before going for any pharmaceutical remedies. I always employed all of the strategies I outlined for you, and in a few days I felt like myself again. Remember that only you and your doctor are going to know best how to treat your symptoms.
I hope you feel more like yourself again soon.
much peace.
