What prescription drug acts most like MDMA in the brain?

I tried mdma over the weekend and had a very positive experience. I know that I shouldn't seek the extreme euphoria that it offers again, but would like to experience that kind of peaceful connectedness on a more regular basis. I've been in and out of therapist offices all my life and mdma achieved (abet to the extreme) more than any therapist could for my trust and willingness to be open. So I'd like to know which prescription antidepressant/antianxiety/mood drug would do a better job of that? I've been hesitant about medications in the past because I've never had good experiences with them. Once I was given Valum for a surgery and it caused me to make a fool of myself. I swear I'm not asking for this for recreational purposes, I just want to be calm and at peace with the people around like that again.
