Looking for advice on PTSD book

I haven't been on my sites for a while because I am finishing up two books on PTSD. The Lost Son is done. The second one, Alive Again is almost done. If you think about the prodigal son, then you'll understand the premise.

Luke 15:31-32

“‘My son,’ the father said, ‘you are always with me, and everything I have is yours. But we had to celebrate and be glad, because this brother of yours was dead and is alive again; he was lost and is found.’”

About six months ago, I was praying to be able to write a book that could help people see God through different eyes and know that miracles do still happen, when people listen. God answered and the Lost Son was done faster than anything I had ever written before. The second one started while I was waiting for it to be edited, and I didn't even pray for this one. I had no plans to write a sequel, but it came out better than the first one,

One of my goals was to cover the causes of PTSD in everyone, not being talked about because everyone only seems interested in veterans. I wanted to include them because I've been working on PTSD since 1982 because of them. I also wanted to include people like me. I survived over ten events but I never see stories like mine in the news.

There's a lot we don't read in the news, so the main character is a reporter who didn't need to know what came after the headlines were written. He became a headline story but what came afterwards was not publicly known, until he told his own story.

The goal is to put both books out as paperback, Kindle and audio. I've been searching online for ways to do all three, but there are so many options, it is hard to decide what to do with these. I've been praying on it but, since I get confused and mess up, like with my first three books, I don't want to mess up on God this time since, He wrote most of these. If you don't know me, then you need to understand that I do have an ego, so for me to admit there is no way I could have come up with this on my own, it's really hard for me to admit that.

So, since most of you have been reading this site for years, what should I do with them? 

Should I find an agent? If so, then which one?

There are way too many online. It is fiction, spiritual, but written for people who do not go to church. In other words, with they way most of us talk. Its about suffering and miracles but is also a mystery/suspense.

Should I use a small publisher who is taking submission without agents? If so, which one?

Should I self publish on Amazon again?

Should I raise funds on Kickstarter, print and distribute them myself?

Any ideas are a blessing. Please give me some advice in the comment section and end this confusion for me!
