How Long Does This Withdrawal Last ? I't Been 2

How long does this withdrawal last ? I't been 2 weeks and I'mgoing back and forth with the drs office and the insurance co.. Meanwhile I can't sleep. I take small naps and my skin is crawling , I 've been tripling my clonazepam up to 6 mg daily just to calm me down. My cymbalta 60 mgs I'm taking twice daily. I did ursine test yesterday and the dr put a rush on it. So I just sit and suffer. Any advice?
