She's just trying to get you to focus on your studies and eat healthy. And why does anyone listen to anything other than John Tesh music?

I'm not sure how exactly that'd work out, but couldn't you contact CPS? While you're close to being off age, you're still a minor, and therefore should be allowed protection from an abusive tutor, especially since your parents passed away. In France we have a procedure called "emancipation" which allows a minor at least 16-years old to be legally treated as an adult, is there something similar in your country maybe? Also, in the event you inherited some money from your parents, make sure your aunt does not have access to it. At the very least, since you're 16, you should have a lot of agency in deciding who your tutor is. Hopefully you have other relatives that could take you in?

First off, Losing parents is hell. Im sorry for your loss. Your aunt is grieving too though, she lost a sister or a brother. Hopefully you can figure out her style and adapt.

These are tragic circumstances, OP lost her parents and aunt lost her sibling. And it sounds like Aunt has no real experience as a “parent”. I sympathize with OP and with the aunt. Hopefully the relationship will stabilize and become more “normal” once the two of you adjust. You cannot change your aunt’s personality and values, but you should be able to help her understand that you need more understanding. Many people who are not parents think they would be much better than actual parents but often badly misunderstand the need for give and take in the relationship - especially with older teens. Sadly you are likely going to have to learn to deal with aunt’s vegan food because she probably does that out of personal conviction and is not likely to start cooking non-vegan. But it won’t kill you and you might actually see some health benefits. But it doesn’t mean you have to be vegan outside of aunt’s home - Just don’t rub her nose in tasty non-vegan food you are having outside her home. There is one more possibility - It is just possible that Aunt doesn’t really like being a parent to a teenager and she’s making things intentionally unpleasant for that reason. That’s something you would have to have a heart to heart, non-judgmental talk with aunt. You could start by telling her how glad you are that she took you in under these circumstances and then move on to asking her if the situation is working for her. You might find there are things she’s equally unhappy about and maybe you can find some compromise.

My double condolences! And I hope the year will go as fast as possible for you OP!

get imancipated sorry on the spelling. sorry for your loss OP. you don't need to live in hell just to survive.
