While your parents have your best interests at heart it sounds like they don’t realize they are making things worse. The correction for this is to move out sooner rather than later. Stop trying to change them and change what you need to do to move on.
You lived in another country—so living away from them is obviously possible. Gather the financial resources you need to make the move and get your own life. This may be the best way to preserve the relationship with them in the long run.
