Accept that there are many players who have cleared everything in the game, so the fault does not fall with the game. Get rid of the mental block that says "this is too hard" and turn it into "this will be awesome when I kill it".

Also, stop crying on the forums to make things easier. It's irritating to see fun stuff get destroyed because people don't want to get better and instead want to bring the fight down to their level instead of rising to the occasion.
