Plz read be4 saying anything.I have ques 4 socialworkers & ppl who know bout children services? marriage relat?

Far as I know I did nothing wrong.a nurse didnt like me so she called children services. I have asked my case worker sev. times what I did wrong she tells me I did nothing wrong. she jus wants offer me services so I dont lose my kids. to me it feels like I lost them bc they put me on a safety plan. I had to find family for my kids to stay with.I am aloud to see em everyday before ten and still have custody. on the safety plan paper it says they having it bc mental health issues and im not capable taking care 2 kids. I keep doin everything prompto after they tell me to do it. theres been no court involved.they wont tell me how long the safety plan goin to be. they have been very kind to me but I was taught not to trust children services. do you think they are playing games or really want my kids bk with me? I have no problems coroporating. my case worker told me I have impressed them. I jus want my kids 24.7 gain. I am so scared of losing em. is children services telling the truth? i did my parenting ane ped house inspection yes i have plenty of food but am single nd no job.yes my family helps me.i also did mental evaluation.we are waiting for results. once we get results i have to take cognitive test. i was working w help me grow be4 dcs got involved.how much more do you think I have to do and how much longer nd are they telling the truth bout tryin get my kids bk home w me or are they lying?
