Worried and anxiety about court

Hi everyone next week is court for me and my ex over our children as there are in foster care as they were taken off my ex as she neglected them when we had spilt up so next weso is the final 3 days hearing now over the 2 year old boy who has been in care just 2 years social services what to have him adopted which I feel is the right thing for him as he is doing really well I've never seen him but I've been told how well he has come along my other older 4 are in foster care now it's just the 2 year old . my ex hates me cause I have sided with social services but I want the best for him and I know this is the best thing for Daniel so am worried if the judge will agree or not and my ex has a go at me at court like she has in the past please can anyone support in any way am really stressed about this it hurts me that they are in care but I know they are safe and really happy thanks Michael
