If you think it is too low for you then go ahead and resign. See whether you can upgrade your qualifications for a higher pay. I am also a degree grad and I get half of your pay and I am in the banking. I have narcisstic parents too which keep comparing my pay to older siblings. Don't fall into higher hope where you are not prepared. If I were you I would do masters to polish my CV, knowledge and as well as good pay offers. All the best.
