What you describe seem to be people with narcissitc traits. Utterly controlling, want to sabotage your life on porpouse, they treat you like they don't want you to be there, but, on the contrary, they actually want you to be there so they can keep on abusing you.
First, I suggest you to look for information on these kind of people and observe their cicles. There is usually a cicle about how they behave.
This is a good place for such, I find:

If any of the stories sound like something similar to what you live, then yes, they are probably narcissistic parents. It is not uncommon, but it can make you feel very lonely.
I have personal experience with this, although mine are different from yours. There are different levels of control and it may boil down to context and how much impunity they think they have.
Isolation is also a common tactic from such people, which is one thing that would explain why you don't really have anyone else or, at least, you feel that way.
These people always have tactics, so you should make ones of your own. You may live on a chess board.
AoP and lots of meditation can help with this. At least, to make thing somewhat better. But what I found works the best is literally binding and cursing them. Another thing that works with them is psychic vampyrism, but only after AoP, knowing how to clean, binding and cursing. These type of people usually take the life away from you, literally, they suck out your energy and vitality. So, the type of psychic vampyrisn I am suggesting is more like "give it back to me". They may take away opportunities in life, luck and put blockages. So that would also explain bad luck, apart from planets.
Hope it doesn't ruffle feathers, but this kind of "parents" don't act as such, to the point you don't feel them as your "family" anymore, except on the amount of control they have over you. I don't believe that family should only be determined on biology. You could be literally be born to psychopaths just because they decided to have children, and then what? You justify them? You let them destroy you because they are "family"? Of course not.
Given they don't really think like a real family, I will elaborate on their real thinking. They are using a position of advantage against you. They are older than you, they have a house, they have some money and they have a bond with you. They use all of this to create their own personal pet or slave, whatever your situation is. What they are most afraid of is losing control.
You will need detaching too. Cutting the cords and freeing the soul:
If you are psychic enough, you may be able to feel just how negative, dirty, chaotic and even evil these people are. It goes to different degrees, so only you may be able to tell in your case. Also, how much spiritual power thay themselves have (I wouldn't underestimate this).
There is no ONE spell that will suddenly take them away from your life. You will need more of an arsenal energetically, at least while you are still living with them. And even if you go somewhere else, so they don't come back demanding something or acting nice.
Don't discard studying just because it may not seem to save you right now. It will help you on the long term. Plus, if you have the opportunity of going to University, you will meet new people and somewhat get away from their control. If you can't go to a place to study right now, try searching online. There are free courses, including the asincronic ones, where you don't need to follow a specific schedule (so they won't sabotage that), including both for increasing your employability and for just knowing more.
These are just some I know:

Do learn about your rights, by the way.
I don't know in which country you live, as it works different everywhere, but you also seem to be describing a situation of domestic violence. That's not legal in certain places. Or is a least a contravention and deserves intervention by the State. But, again, I don't know where you live, so I suggest you look up for services for domestic violence and violence against women in your country and zone. And also check out how it works there.
These people cannot be changed or negotiated with, so don't put your energy on that. Or even thinking about that. Also, if they suddenly start being nice, don't fall for that: it's a trap. It may happen when they see they don't have as much control over you anymore.
So, do the basics of meditation, and don't be afraid to bind them and curse them. They are the kind of people to be really sticky in a way and be over you, controlling. They don't want things to be better, as it doesn't serve them.
And keep your projects in utmost secret. Everything about getting out of there, everything about studyng, working, having a career, a friend, a secret.
Also, narcissists follow a certain rule: they are as bad as they are allowed to.
