We all hope we have HELPED you with options you may not be able to think about in your present state of mind as it sounds overwhelming and again I hope I have helped with options that will better your situation.
The honest truth is sometimes life deals you a crappy hand, politics aside, there used to be ample services available for the hardest hit CA residents and now they are overburdened and ineffective for those needing them the most.
You can't delve into what was last year, you'll never get anywhere forward.
Family can be found in churches or support groups maybe in your area.
My heart goes out to you as it appears you are struggling and it is wearing on your emotions and ability to stand back up, the best thing is to be around people who may be able to assist you, churches would be the 1st place I would check with and beyond that reconnect maybe with family that is out there that you haven't had contact with.
You mentioned you son or sons earlier, talk to them and see how they can assist getting you back on your feet or helping you find services.
Sorry to say but this is a real estate forum and not oriented for outreach programs or social services so you may not find much value on this forum but I do wish you the best and hopefully you can find the strength to move forward and find some direction.
Have you tried these options?:

I agree with Bruce, perhaps you should consider moving out of state where cost of living is lower.
Meanwhile, you should try to contact local churches, and charity organizations. Perhaps, they can help you. God bless you.
Maybe it's time to look at some of the surrounding states for more affordable accommodations.
I hope your situation improves soon and hopefully life starts looking a little more positive for you
