Child custody

I'm not sure where to begin, or how to ask for help from anyone, but I know I have to ask now. I don't have any expectations because I'm aware everyone has their own lives, loved ones and struggles. I've been back and forth through courts, with lawyer fees, drug and alcohol assessments and psychological exams to prove that I'm a stable parent since Emma's birth, and because I feel it is in her best interest to remain primarily in my home and not a 50/50 custody set up. In saying that, please know that I am not angry or resentful towards her father and I do want her to have her family, every member in her life always. I have spent the most part of $20,000 of my money, my mother's retirement fund and from the help of several people that were kind enough to loan it to me. I am now in a situation where I don't know where to turn to keep my head above water. I'm surviving please know that, but I just found out today that the last doctor involved in my daughters case will be an additional $5000+ I'm asking for any help that anyone may be able to contribute and please know this is utterly embarrassing and humbling all at once, I just don't know what else to do. This was not easy to come to all of you, the people I respect and that respect me with something so real and vulnerable, but I couldn't give up on Emma,  the life I created inside my body without asking for any support first. This is all and always will be about Emma and what's best for her. Thank you all in advance for even reading this and taking the time to consider.
