I'm scared of my dad, what do I do?

Tell him that he's bothering you,leave a note ,send him a text or something maybe he'll change because when you tell someone they are hurting you more than helping you especially parents they try to change if they really care and if he doesn't he'll be more aware

It's important to think deeper about why you are afraid of your father. If he is a potential or immediate threat, you need to reach out to someone and contact the authorities when required. If some past hurt has made you afraid it can be helpful to seek a family counsellor to help work through the pain and learn to trust and forgive your father again. If you aren’t sure why you are afraid, talking openly about with your father can be more beneficial than keeping your feelings to yourself. You can also ask another trusted family member to mediate the conversation if that would help you feel calmer.
