This. The song didn't make me cry in a happy way, just a very bad-memories, mopey kind of way. The reason is because this song reminds me of my Mom's life (As told to me by herself and my grandmother) and it depresses me, thinking of everything she went through. It is also very reminiscent of my, lets just say...less than fun childhood.
As a kid, whenever I found myself in a very uncomfortable situation, I would dissociate myself from my surroundings until I disappeared. Having found this song about three years after I stopped doing this, I was reminded of what a socially awkward child I was, how often fear of people brought me to terrified tears and the way stagefright would completely destroy me in front of so many eyes. The song made me a bit emotional, especially at 4:38 where the singing becomes a part of the background, and at 5:00 where the song begins to collapse.
