my parents are disgusting...

My mother and my stepdad are so filfthy and disgusting... they do not care about their house, their room looks like a homeless room.. it's shameful and so dirty, i can't even go in there... I bought them a brand new bed (to encorage them) and they completely destroyed it.. they never put any bed protector sheets on it, the matress looks brown... they manage to break the bed too... totally digusting! why are they like this?! I also bought a new clothing rack and they already broke it all... wtf is wrong with them?! Are they mad or what... My mother was never like this when we lived with my father... the only problem was that I was highly neglected like she used to never shower me (i showered myself for as long as i can remember), she would leave me at home alone sleeping while she went to the bar... and so on. I have a bf, i feel so ashamed of them! They don't even have a wardrobe.. all their clothes are on the floor, the walls are not painted... omg they really have detroyed my self esteem growing up... and feel ashamed all my life of my family
