Kid, you've done nothing but whine and moan and complain about breaking your keyboard. Others have tried to explain to you what you're doing wrong, and you've consistently chosen to ignore and even deride them. If you'd read the manual or even just look at the attributes, you'd know you need more than just Dexterity. Perception, Speed and even Constitution are necessary skills. It's not the games fault that you don't pay attention.
Perception: Affects your critical chance, initiative, starting AP in combat, ability to detect traps and accuracy when shooting over long distances.
Speed: Affects your movement speed, initiative and how many AP you can use in combat.
Constitution: Determine how much vitality you have and max number of AP.
Dexterity only affects your chance to hit, but is not the end-all-be-all of using a bow. You need points in other attributes.
