Feeling guilty for snapping and worried about neigbours reporting to social work

[anxix]

I'm having a lot of issues with my downstairs neighbours they have a noise app because the kids foot steps are too loud. They've complained so much they had to give them the app but I'm told not to worry at all if the kids are too loud all that happens is my council come out and apply more flooring.

But today my 6 year old kept going to hit my 2 year old.

I never shout. I hate it but she wouldn't stop so I had to raise my voice not shout but raised and said stop. Stop it now please. I said it maybe 5 ish times.

The raising my voice was over maybe 5 mins and I only said stop it please then go away

Then she wouldn't so I had to shout go away now meaning from her younger brother

This is bad I know but could it lead to anything social work wise I know fine well she's an evil lady downstairs and will have recorded that

I apologised for shouting go away and explained she just cannot hit her brother.

I'm maybe just feeling so guilty because i never raise my voice and shout. I feel this way every time I tell them off

No OP you have done nothing wrong at all.

You are fine to say that. Children need boundaries. You didn't swear. You didn't name call. You needed to stop the hitting. It sounds like you did the right thing. Downstairs neighbour sounds awful. Can you get rugs from a charity shop to muffle the sound??
Also the neighbour probably has a reputation as a trouble maker keep your own record of the mean things they say to you so you have a record if they complain.

What do you think is going to happen even if she does contact social services? They don't remove children for being shouted at, especially a one off. You're, understandably, being hypervigilent
