If someone says another person is a "biraz rahatsız" person.

What would that mean? I think that would likely mean they think that person is troubled.

That could mean 2 things, 

1.  He is a bit mentally disorder.

2.   He is a bit unwell. (not feeling well )

Thankyou

I probably misunderstood something. I was talking about a sibling´s son. The response was:

Bizde ablama gidiyoruz oğlu biraz rahatsız o bu sormaya.

So I thought the person was calling the sibling´s son rahatsız. So I said he´s not rahatsız, I said he´s fine. And the response was this:

Yok o değil ablam ın oğlu rahatsız onu sormaya gidecez dedim.

Could someone translate the Turkish. Is it written well or what would the corrections be?

There is one more correction to be done. Biz de, not bizde. İ assume the sentence came after they asked you what you are doing, you told them and then the other person started telling you what they are also doing. Am I right?
