If you do that your VERY likely to die! I am a christian and I have decades of wilderness survival experience and training. My uncle was a Col. Green Beret who taught me survival skills that his men had to know to survive. I spent an entire winter alone in a hand made shelter with nothing but a tarp, rope and strings using the local materials such as branches, tree bark and leaves. This was in the mountains of Idaho near the "river of no return". Despite my training and a sleeping bag rated for -40 below zero, parka and winter clothes I almost froze to death. And I was skin and bones come spring despite eating all I could find, trap, shoot or gather. So if you try this you WILL die. Listen to what others are telling you here about stupid cults that tell you the Holy Spirit is going to feed you. Not going to happen! God gave us a free will to do as we wish so we can be stupid as we want or as smart as we want. Doing what you said is NOT smart.
Now to get out of that human cesspool of California. I moved there and worked construction and saw it was a unholy mess so I moved out! To get out requires two things; determination and money. You could work as a farm laborer and camp out with the other farm laborers who are mostly latino. You save all you can, eat a healthy diet then buy a bus ticket and get out of Cali. Starving causes the brain to malfunction where you can no longer reason things out. I was talking to myself after 6 months in the wilderness because of that. You need to eat NOW!! There are many nice places you could move to that dont get below zero, that have good jobs, low taxes and reasonable rent. Fasting now and then IS good for you, eating nothing is BAD for you! You do not have the skills to survive 'off the land'. And even if you were an expert you will still have a very difficult time! Living in a tent near L.A. makes you a target for gangs, killers, mountain lions, black bears, wild dog packs and it puts you in danger of forest fires.
You really cant reason this out until you eat well for a few weeks and DROP that insane cult starvation crap! Good luck. You sure need it!
