I cant kill anything

hello i cant kill anything (without my wabbajack and that takes awhile) and all my items are enchanted with fire damage and i can hardly kill a frost dragon...

Did i metion i am a level 20 and i have a huting bow and skyforge steel sword (hunting bow improved twice) all

with 10 extra fire damage and burning damage. Where can i find a better unenchanted one handed wepon or bow?
