seriously just go away .... OP theres lots of great advice here so keep pushing forward diligently. as others have said its all about the preparations, gear up in your best available gear before you ever venture out to the next biome, best piece of advice you could possible get for easing the frustrations.

again as others have said, its easy to get deterred if you are trying to rush into situations you aren't yet prepared for. good luck and by Odin's will you shall be victorious! :)
