Have you killed Bonemass already? You need to be properly prepared to survive the mountains, actually any biome. Mountains are harsh if you don't know what you're dealing with. I recommend using the secondary attack of the iron atgeir against wolves, because it can stagger them and then they're easy to kill. Drakes are no problem, as you can just pick them off with even a finewood bow and flint arrows. Needs 3-4 arrows. Once you get obsidian it's much quicker.

Don't give up. Try again. You learn something every time you die.

Oh yeah, stay away from golems for right now.
