I had crippling social anxiety throughout my teens and into my early twenties. I had fully accepted that I would always be alone and I was happy for the most part. This all changed around age 25 as I (seemingly all of a sudden) became physically attractive enough for women to be interested in me. Without wanting to go into too much detail, my life was turned upside down and I started to learn lessons about people, society and relationships that I feel like I should have learnt 10 years prior. I no longer have social anxiety and can have meaningful relationships with people.
During this renaissance period I did use MDMA. But what did it do for me, if anything? Did it enable me to learn these lessons in a way that a normal 25 year old wouldn't be able to? Or did it show me things I wouldn't have seen otherwise, but were still within my natural ability to learn? Or was it simply a fun thing I did but ultimately I would've got where am I today anyway?
My feeling is the drug did help me, but I wouldn't just recommend it to others in my position. It won't do anything for you if you just take it in your bedroom with no other changes happening in your life. But if you find yourself, like me, learning how to be social much later in life, it might be worth a try. It won't harm you if you do your research (read erowid).
