Please help me, I'm at my wits end. Worlds biggest failure

[starshaker]

My DD2 (7) its behaving so badly. I don't know what to do. I don't know where to start.
A few weeks ago she was grounded. I got up in the morning and she was gone. She was at the park down the road. She told me there was no point grounding her because she would just go out anyway.

I tried removing things and she doesn't care
She misbehaves at school
There was 1 day she was playing in her bedroom, only she wasn't. I got a text telling me she was knocking on peoples doors trying to sell sweets. I went out to find her and I couldn't. After an hour of looking and calling friends and putting a post on Facebook i gave up and called the police. She turned up as i was on the phone. She had gone over the road and was playing beside the burn.
I caught her stealing from asda and made her take the toys in (it was a balloon and a set of bubbles). The staff didn't care and she thought it was funny so I took her round to the police station. She still thought it was funny.
Tonight she has cut my sofa with a knife. Theres a 4 inch gash in it.

I don't know what to do. Im a complete failure. I have tried everything I can think off.

That does sound extreme. What did yiu do when she went to the park and went out without you? Are you looking the door now and hiding the keys? What did you do when she stole and slashed the sofa?

Have you spoken to the school and your GP?

[starshaker]

Ive been to the doctor 3 times and I am in contact with the school too. When she went out I banned her from treats and choosing what to watch on tv (i can't ban tv because I have 2 other children). I feel like I can't do anything that will help

[EveryoneTalkAboutPopMusic]

What she the GP said stars? Have they referred your DD?

[starshaker]

yeah she behaved badly in the doctors which is a good thing. Showed him what i deal with and how she just doesn't pay attention. We have been referred but it could take months

Can you lock the door to stop her escaping?

[starshaker]

I do lock the door now but if my son or other daughter goes out then I won't lock them out. Ive given up grounding now because it doesn't work

[EveryoneTalkAboutPopMusic]

How old are your other children?

[starshaker]

7 and 12

[EveryoneTalkAboutPopMusic]

If you’ve got a 12yo and two 7yos, one of which has taken to wondering around by herself, you NEED to lock the doors. It’s a matter of keeping her safe.

They are normally allowed to go out to play but I need to know when they go out and where
