Being "railroaded" so that the transition of my daughter's adoption cannot be contested by me...

Until 5 months ago I had been chronically homeless for 14 years, and during that time I had a daughter with someone who was also homeless at the time (who left the streets long before I did). A couple of years went by and I saw her with my daughter (who she denied, at the time was mine). Inevetably after her rebuttals toward me being allowed to see my daughter, I ecxplained to her that I would seek court assistance for visitation rights. She told me that if I did that she would retaliate by "hitting me up for child support because I would be killing her hustle", (apparently she was lying to another man, saying that he was my daughter's father, and truly knew that he wasn't- despite the obviousness that me and my daughter was identical n appearance). We went to court, and paternity was established.... I was "hit for child support" but disallowed from visitation "due to my living status". This past winter I began getting letters from Illinois child support enforcement explaining that I owed over $9,000 in back pay to her mother, in addition to over $2500 in back pay to DCFS. I then found out that way that my daughter had been in foster care and is apparently now up for adoption on May 12 of this year. I immediately began seeking information
