Lost 3000 souls, got pissed off and turned off the game for now.
*J. Jonah Jameson Laugh*
As someone who has put around 600+ hours into the entire Souls series, this is really funny for me to read.
I mean, losing 3000 souls is nothing. Dying in the Souls series is an integral part of the experience that is also connected in some manner to the lore if you are into that. And yeah it sucks when you lose more than you want to when you are trying to advance, but in most cases there's always a way to advance, just be sure to put attention to your surroundings for any enemy and explore a lot.
All that said, is good to see that despite you are struggling with Dark Souls you are having a good time with it. Keep at it man! :)
