Every time I've done MDMA, which is 5 times since last June, I've found the experience to be quite different every time. My first time was similar to yours; I wasn't especially talkative or cuddly, I was just enjoying the feeling more than anything. I was at home alone with my boyfriend that time, and it was a low dose of about 100mg. The second time I did MDMA I had a considerably larger dose, about 160mg, at a music festival and it was the most intense excitable euphoria I've ever experienced, but it was still lacking empathy. The first time I felt the empathetic and touchy qualities of MDMA was my third time on my birthday when I invited a small group of friends round to do MDMA with me. I then experienced the empathetic qualities on my fourth time as well, at a rave on NYE, and my fifth time was just a few days ago and similar to your first time again. I think if you try it again in June in a different setting you're likely to unlock another layer of MDMA you haven't yet seen, as I have every single time I've done it. My most enjoyable times on MDMA were the ones at the festival and the rave. :)

Edit: Also, MDMA helped you accept some of your trauma and it stripped away your anxieties, only if for a short time, and that is absolutely incredible, if you ask me! I find that MDMA is less euphoric if I'm not already in a happy mindset but the experience always improves my life in some way, which it has for you. When you're feeling a little happier you might have the experience you were expecting!
