I Really Miss My Belgium's House

I am seriously missing the small Belgium apartment where we live before. But I think it;s not the house that I miss but it simply the privacy had when we lived with the four of us. Now we are living in my parent's house but we did not have the privacy like what we had in our small house. That's why I miss it so badly.

I know that we have a better living now but it does not mean that I feel more happy about it. I just don't know what I should do to solve this or to get rid of this feeling...
