owwie.. so tough.
first off, your first two heuksal skills are weak (wolf bite, dancing demon spear). i don't recommend you upgrade those. good for early lvls, but shouldn't be upgraded that high and be able to de-level with the curst heart quest.
i agree with hyionno to keep your skills into a certain area depending on your build (pure int/str or hybrid) and upgrade accordingly.
anywho, you're not too far to start over

you can get to lvl 20 in a day's worth of playing. good luck!
