You have 2 options.
- Continue to be unhappy and complain about your situation.
-Change your situation and hopefully have a happier future.
You can make as many excuses as you want about your parents not "letting you" move out, or do this or do that. But in the end, you are choosing to live by their rules despite being an adult who is more than capable of making decisions for herself.
Yes it will be difficult, and yes it may cause some fights and tension in the family. But you're already miserable so what does that matter? Unless you're at risk of being harmed by your family, I think you need to stop making excuses for their behaviour and for your choice to stay there and move on. It may come to the point where you have to choose between your family and your life, happiness and future. And that is a decision only you can make. But the point still stands that it is entirely your decision.
