going for 0 fg run throughs are extremely difficult and even experienced players spend a good 48 hours or so of actual play to reach level 71.
Main issue is that you have added 0 vitality, as each point of vitality increases health gained each level up by 1 as well as immediately gaining equal to your level in health when you stat it.
So to answer your question, yes the game is supposed to be this hard, If you're able to locate a level 30 weapon which you can use you'll find it significantly easier, or you can ask one of the kind souls on HC if they can get you an item, however especially for HC you're probably better off starting a new character and statting full vitality for a HC runthrough
Here' a topic offering freebies, might have some myself:

on the plus side you have a crazy good tier 3 weapon in that club so getting back to level 30 again shouldn't be too much hassle.
