Welcome Diamond! So I'm not sure if this will help you or not but just in case it does bring you a little peace here is my 2 cents.
I've had my life ripped away from me, found out my daughter (6yo) isn't actually mine. found that out about two years ago and spent every cent I had trying to get some kind of legal right to her, but in Mich that turns out to be in possible because of the family court "best practices". Before this latest trip, she was the only reason I had to keep going now its just another failure on my part. I was all for fighting this battle and keeping my daughter safe and alive and I lost. I would literally give anything to give that little girl a good life and keep her from the pain I've felt. Kids are amazing and can totally be a reason for living, but then you need to focus on the joy they give you and fuck everything else.
At the same time now being in the state I'm in, I just kind of accepted that maybe the best thing I can do for her is just go away, I'm sure this isn't the case with you, but it's another side of the same coin.
No matter what I hope you find peace, whatever that may be for you.
