Newbie, fucked up stats..Start over?

IN LOVE WITH THIS GAME BUT I am new to it and made the mistake of spreading my investment because I thought I wanted a balanced character. I have now read that this is bullshit. Now I'm quite far into the game (Invisible Village Yahar'gul) and realize that in addition to the high difficulty level, I also have too little skill/strength. I like to play with the Saw Spear/Cleaver as my main weapon. Do you think I can still manage the game or should I start over?

Vit 20 End 21

Str 19 Skill 19

Bl 17 (Basically this is the mistake, from what i ve read) Arc 15
