[Always *]

Update your resume and start applying for new jobs. Not only with that (ideally) placate any (reasonable) parent but it is also the responsible "adult" thing to do - if you didn't have your parents support, which I'm assuming you do because otherwise this isn't any of their business, then you'd have to rely on your savings OR find a new job before finding a new job. So I'd suggest operating in this way and quit your job as soon as you can if it makes you feel unsafe. This way you get what you what in the most responsible way possible.
