My dad walked in on me naked

I hate my life. I'm almost 18 and I have 0 privacy and always had. I was in the shower and I locked the door. My lock isn't really good bc it's the type of lock you can unlock from outside with a key or a coin. My mom always unlocks my door if she needs something (yeah she can't wait 10min until i get out) and I've told her before I feel uncomfortable especially because my dad can walk by and see me while she enters. And I'm not really comfortable with her seeing me naked too but if I tell her that she will start thinking I have something to hide and I send nudes or smth. Anyway, she never took my concerns into consideration and always unlocks my door and enters telling me "you don't have to worry about your dad". Well guess what, today morning I was showering and she unlocks my door and enters and doesn't even lock it back. 2 minutes later my dad bursts in to "give her the phone bc someone was calling her". He saw my entire fucking naked body for 2 seconds and I feel so embarrassed and I feel like an object and a toy. I was in disbelief at first and after some moments I started crying. I have this suffocating control from them my whole life. I feel so violated. My mom sees me crying and she tells me to not cry, because if my dad notices he would go crazy because he would think I thought the "wrong thing" about him (that he did it intentionally like a predator). I hate this fucking family so much. After a while my mom gets out of my bathroom and doesn't even lock the door back with a coin. She tells me to "get out and lock it myself. I haven't heard a single apology from my dad. They always love violating me in every way they can. I feel so shit and I feel like I've disappointed my boyfriend because I want him to be the only male that ever sees me naked.

edit 4: a lot of the comments are telling me to get a job and move out. people don't get its not as easy as it sounds or seems to some. firstly i have to study for my finals and i'll never have time for a normal job. secondly i'm from the east and live in a small country with horrible part time jobs salaries. i could never afford to move out and be independent financially from such a job, so the only option i have is to wait it out for 5-6 more months until i go abroad to study.

edit 3: you all say my dad isn't a creep but he literally made some inappropriate comments about my boobs and ass growing after i hit puberty (13-14).

edit 2: my dad is an abuser emotionally and in the past he's been physical too. stop telling me he is my dad and he's seen me naked before. you can't compare me as a baby to me at 18. i hate him with my whole life and i can't bear him (or any other man) see me naked as a girl.

edit: i cant block the door with locks, stoppers and other things because my mom will start yelling and giving me anxiety until i give in and unlock it
