Religion: my parents are psycho and make me feel bad?

i live in a house full of religious people they force the bible on you, and can make you feel bad about not following god. they constantly talk about the end and say everyday the worlds going to end be ready. so they sit around watch tv eat like hogs and yell at the tv saying ' their all sinners! theyre liars!' ..they dont go to church cause they think tithing and preaching in a building is wrong. its driving me crazy they made me so afraid of god that i can barely live my life. i feel like everything i do is a sin and i'll be punished.. a few mins ago i slammed the door on my stepdad, he yelled out ' it will all be over at the while!' ..what is that suppose to mean?! is that a threat? see what i mean.. and that freaked me out now im paranoid thinking whats going to happen? someone please help me how can i put up with this. i feel guilty for everything i say. if i say 'hi' to someone, i feel like i sinned. they got me so wimpy and paranoid, what to do?
