(long message Inbound, if you dont want to read it, you don't have to. I pretty much tell the story of how i became a brony... and how it changed me)
Dude this show has changed my life immensely I'm not joking, before this my life was one big depression, Nothing went right for me, I was always angry with everyone...
One day I saw that Teens React to MLP, I watched it and I thought "Wow, that has to be the strangest thing, guys liking My little pony, wtf is up with that?" But then I thought, "Hey maybe I should give it a chance, I can't hate something that I haven't seen before..." so then I watched the first episode, at first i was like "wow I cannot believe i am watching this." When i saw it was a two parter i was like "eh why not i will watch the second part" I finished it and I said "one more episode... and i will say whether or not i like it..." Which then turned into another episode and another and well you get the idea. At the end of season 2 I looked at my screen and said "This... is... amazing..." Right then I became a brony, and even though my life still sucks sometimes, Ponies make it a better day. I love this show and fandom. (sweet Celestia this is a long message )
I am very happy for you, I've read about several situations in wich MLP FiM saved countless lifes. This is no ordinary show, it has something special that you can't explain. I never really had an opinion about the show before I started, but then I stumbled upon the .MOV parodies on youtube, and thought it was hilarious. After a few more vids, I decided to go check the first episode, to see what all the fuss was about. After the 2 first episodes, I was completely hooked on the show, and proud of it. So that's how I became a brony, basically.
