I totally second Clepto here ! it's a job opportunity, in your field on top of that, and you're qualified for it : go for it !! What I seem to understand as a slight subtext too (please correct me if I get you wrong) is that you live at home with your family and your mum doesn't want you to leave, like all the mums in the world. This should deffo not be an argument to keep you home, and maybe indeed you want to move out, which is totally fine at your age Go get the job, and you'll see later about buying a home. That's my opinion, you're the one to choose !
