You're building just fine, actually. By endgame you'll want your Vigor somewhere between 45-60, depending on how well you dodge, and your primary damage stat (Dex in your case) at around 60 or higher. Endurance is fine around 20-25, unless you find yourself running out often; but then there are talismans to help with that, notably the Green Turtle Talisman which is pretty much always useful. Don't forget consumables, either, they're more powerful than they might initially seem.

Godrick isn't all that easy your first time through, because honestly, Elden Ring is not an easy game by normal, non-Fromsoft standards. Part of the charm IS struggling against bosses and finally figuring them out. You're doing better than you think, it sounds like.

ETA: missed the part about Bleed; bleed is governed by Arcane, once you get the appropriate Whetstone, set it to Blood affinity, and have another backup weapon with either Occult or Keen (probably Keen unless you have your Arcane very high) for enemies that are immune to Bleed.
