Transgender custody crisis

My son, 5, disclosed to me, on a recording, that my ex, had been abusing him, including sexually for years. She is a cis-woman and of course I am trans. My ex abused me for 16 years and has a long history of it. As a survivor of so much trauma, the one thing I'd hoped was that my child would avoid it. But there were so many signs, so much evidence, it was not surprising. 

Despite the fact, that my ex warned me that they would do whatever they had to make sure I never saw my son again if i ever disclosed anything about her, claiming that they would never believe a trans woman against a cis-woman.

She was right.

Even with a recorded disclosure and emails of her admitting to being an abuser and with me walking in on her abusing him, CPS was so transphobic it paralyzed me in shock and trauma response several times. After never even asking me for evidence, the cis man investigator came to my house to tell me that, I may be fooling some people but not them. They claimed, I had made all of my own trauma up as well as my son's. I had hallucinated seeing her beat him. My 16 years of abuse were a fantasy. But they went much further: I was banned from ever cuddling with my son again without explanation, though of course they think the trans-girl is a predator, I could never ask him about trauma again because it is now official that I forced him to say those things, which they have concluded is emotional abuse and I have lost my kid to his abuser. (There has never been any assertion that I have ever harmed or lied to my kid or anyone else--but my ex made it all up with no evidence and they believed it). 

From my calling with evidence, a recorded disclosure and mounds of emails, I am now seen as a risky person who my son will soon be scared to see if I am ever allowed to see him again. 

The details are so agonizing that it is hard to express and too sad to go on. Just know, he is almost certainly being abused for finally being brave enough to tell someone, because he told me that's what she said she'd do if he ever told. 

To have any chance of even having a chance to see him I have to now go through all kinds of humiliating and expensive steps, including an expensive psych evaluation with an assigned cis man to see if I am sane. There are now lawyer fees. I will have to fight because literally not a single person out of about 25 i have encountered in the system believes me. 

They won't even accept my evidence. None of it, because my ex convinced them I am delusional. 

So I need money.

The quicker I have funds the quicker I can have a chance to see him, although she is moving toward my never seeing him again, as she knows I am the only person who knows what she's capable of. 

Please help.

I have so little hope right now. But for him, I am trying. 

So there you have it.

I need money but somehow am not expecting anything good to happen. 

Thanks.

And please don't send too many well-wishes or advice. It mostly just breaks my heart to read and I am having a lot of difficulty even thinking about what is actually happening.

Thank you, friends.
