What can I do to get my kids back and prevent cps from adopting them out.

I’ve been involved with cps for a while now this is my first time being involved with them. When my daughter was born 04/18/21 I had positive traces of marijuana and I believe methamphetamines??? I also had an STD and no prenatal care as I didn’t find out I was pregnant until I started showing. Cps took my baby right away and later placed her with her sister at a foster parents home which was related to only one of my daughters. I began reunification services right away (they didn’t take me to child family court or whatever it’s called) I was given a case plan and told once I completed everything on there I would get my kids back… I did everything on that list in the case plan I even went past the 6 month evaluation and got an extension I completed the classes got a stable home for us found work and went to get assessed by BHRS and I have the results which stated I didn’t meet criteria for services. I took that back to my case worker and they called me a liar told me to go back.
