Trouble Finding Carp

[worstfishermanalive]

So I live in El Dorado and have fished everywhere I could think of including but not limited to: Moro Bay, Felsenthal, White Oak and Tricounty Lake. I have used pack baits, bread and sweet corn all using hair rigs. my current setup is 12 pound line>.5 oz egg sinker>helicopter>swivel>8 in braided line>#6 hook with hair rig. I just got done with white looking for grass carp, chummed the heck out of it and not even a nibble. That is what's really freaking me out is no fish has shown interest in my line. I can't figure out what I'm doing wrong, it's getting to the point I'm thinking carp are all part of my imagination or maybe a persistent hallucination. I've gone for common, hybrid and grassers where ever they say they are I go and can't find them. If I ask people just tell me to get a boat but I can't afford one nor really want one. Do you guys have any suggestions of what I'm doing wrong or where I could go to catch them? My sanity is starting to erode I've been trying for a few months now just fishing on the weekends and nothing not even nibbles.

Thanks for your help!
