<human>: Life has been very hard on my brothers (17/10) and my mom (40)... We left our abusive father because he would constantly hit my mom and drink a lot.

My mom was a SAHM and never really worked before so to escape my father we had to live with my grandmother and our two uncles.

One of the uncles was our father figure basically and we loved him. But, he got a girlfriend and moved out to live with her... So we were left with our other uncle that would say incomfortable things to us, would verbally abuse us and at one time... He even hit my mother, gave her a black eye and a broken nose.

My grandmother said that if she went to the police, they would kick us out so for our sake, my mother remained quiet. 

A few months past and this abusive uncle left to Brazil because he found a job there. My mother started going to night school to get her HS diploma and got a job at a field she loved... She got enough money, to find a lawyer and finally divorce my dad and sue him for child support.

Things seem to go great, we still live in our grandmother house and we made it our home where we had happy moments, finally...

But today, my grandmother got a call from our abusive uncle saying that he's coming to Portugal (where we live) because he got fired and needs to come here to sort some papers and stay "a few days"...

I'm a mess since I heard his coming back, I can't stop crying and having panic attacks... I've told my mother via text that he's coming but she hasn't replied yet... I feel like everything is falling down and I don't know what to do...

Could you distill the essence of the text into 1-3 sentences?
<bot>: My abusive uncle that hit my mom is coming to live with us again maybe and we don't get a say on this... We don't know what to do??
