wibblewobble, having had one bad experience with SS (or read something bad on an internet forum) is absolutely no excuse for not seeking help when your child is at risk
I have had a horrendous experience where taking my child to hospital resulted in misdiagnosis and dh and me being suspected of sexual abuse
does that mean I should never have taken dd to hospital again?
have also been investigated by SS and the EWO
but would never ever have considered not asking for help for my child who was suffering because I was afraid of unpleasant things that might be said about me
how could you justify that to yourself?
it wasn't about me
if your child needs help you run to get it- you don't stand around thinking "but they might criticise me"
I have had a lot of nasty things said to me in connection with dd's disability/MH problems
but I have also got her the help she needed, she has been able to grown into a fully functioning adult, she can look back and see that I never gave up on her
surely that is worth having a few nasty things said to you?
even if this 16yo moves from home, somebody is going to have to see to it that she is all right and gets help with her problems- whether that is the OP herself or the OP engaging with various authorities
the younger children are going to need support and quite possibly counselling after what they've been through
