What exactly do you mean by afraid he will come into your room and do something to you?
Do you think he will sexually abuse you?
And honestly I agree with some of the other comments.
You need to tell one person. Someone you can completely trust to tell and talk to them about it while you try to gather the srength to tell someone else with more authority. Because if he is abusing you then he needs to be put away.
Only if you do that you must make sure that he isn't going to run or find out until the police get there.
Or call CPS and ask them to get you out and tell them what has been happening to you (only when you're ready) Also explain to them that they can't let you dad have even the slightest clue as to what is going on because you are afriad that things will get worse.
