Accidentally looking into someone's house

I have 3 mental diseases ocd, psychosis and split personality disorder. And sometimes I look at windows of homes when I am not in control and I am stuck in a position to try to look away from them due to it being a sin. I unfortunately sometimes choose the wrong direction to look away from them for example, The window will be covered in a curtain but the sides will be left blank due to the curtain being too narrow to cover the whole window. Do I get a sin for accidently looking into the house in that matter or when I see just the darkness of the room from the sides in this case?
