Wondering what to do next

I told my aunt, my dad’s sister, what he did to me when I was six years old and all the ways I’ve been struggling and her reaction was good. I asked her not to tell anybody and she didn’t, which honestly kinda surprised me and now I don’t know what to do next. She advised me to get away from him, which is fine, but it also poses some practical issues; my grades are slipping and I might not graduate this semester, and I’m afraid I’ve really let down the professors I’m close to. My parents and everyone else who’s actually been good to me; meanwhile I’m gonna hear a whole bunch of judgement from relatives, including my parents, blaming my problems on laziness and drug use. I can tell everyone the truth but that will blow things up in my family and might just look like me making excuses to others. Everything feels like it’s falling apart and if I run away I’m just leaving a huge mess behind.
