Since you live in Turkey, you can live not in a secular, but in a religious family, or in a very conservative family (as in the Middle Ages).
Since your parents may not be adequate and may not want to let you go, perhaps you should consider a more subtle option of separating from your parents, since you are an adult and can legally do this.
For example:
Step 1: You can tell your parents that you want to go to college or university and live on campus or in a dormitory at an educational institution, so your parents will see that you are studying and you will be able to separate from them (your parents will think that this is temporary).
Step 2: When you study, you can work part-time in cafes, McDonald's, or even at college/university in the evenings, many students do this and you don't have to tell your parents about it when they visit you. This way you will have your first money.
Step 3: When you study, you are not alone, you have peers, you can make friends with some, you can also find friends among students who find themselves in a similar situation, having joined for a while, it will be easier for you to study, work and help each other together. If you're a girl, you shouldn't have a problem with that, girls help each other. The solidarity and mutual assistance that I see among women, I don't see so often among men.
In step 3, you study (get an education to find a more prestigious job) and save money from part-time jobs. When you graduate and you have a basic cash reserve for the rent of your own housing, you will be able to move to another region of Turkey, live separately from your parents and work, lead an independent adult life.
