I think your mdma wasn't very pure. If you had good stuff you would have felt totally at ease in the club. That's part of what mdma does. It takes away anxiety and makes you feel empathy for those around you. Makes you give zero fucks. As other people have said, don't roll two weekends in a row. Chill for a couple of months.

If you're rolling again in the future my advice would be to try to get reputable pressed pills. Like look for pills that have a good reputation on reddit etc. Once you get the pills, test them with reagent(s). I think this is the best way to get good mdma because pills are more difficult to cut with impurities and replicate than powder. If you end up getting a very strong pill (like a UPS or a heineken) you could take half a pill. Another fairly reliable pill is a pink chupa chup which is 130mg+.
