I've been there. Don't give up. You've obviously put in alot of time, don't quit now. When I finally passed I focused on being more organized and condensing my study material. Stay positive.
I also think you shouldn't spend much time studying from the CERM. I had four books of example problems and only used the CERM as a reference. All I can say is, work as many example problems as you can. Refer to the test outline that the NCEES gives you and make sure you've done examples...
The morning Civil PE exam I thought was relatively easy. I only doubted my answers on 4 questions. The afternoon Geotechnical exam was difficult for me. There were more conceptual questions than I had anticipated.
