Ok, a couple things - fatigue is the most important factor in this game, especially at low levels. If your fatigue bar is low you're not going to do a single thing successfully, so take your time, don't always run, or else rest
often to restore it. Second, you really want to make sure you're using a weapon you're skilled in. By the end of character creation your main offensive skill should be at least 40. I hope you paid attention to what kind of weapon you bought, as well. Long blade vs. short blade matters a ton.
Don't give up on the game yet. You'll hit your stride around level five, and it only gets better (and surprisingly easier) after that.
