To come home or not to come home

Just learned I got this part-time job..yipee!  And so, this means more hours of being awake and being tired.  But, have to do it as my landlord said that rent would be increasing effective next month so I had to prepare. 

It has been my "tradition" to go home to my parents and spend the weekend there whenever I am to begin on a new job.  But this time's different.  If I go home, my expenses will double compare to the scenario of staying in my small flat.  Whenever I'm home, I felt obliged to do the groceries, cook for them and give them a few cash before I go.  I am happy doing that, but then, I have my own responsibilities also.  I love my folks and even though we almost always disagree, I'd serve them and give them extra cash even if after I arrive back here at the apartment with only noodles to eat.

Now, I am confused if I'll go home.  When I'm there, I feel relaxed and rejuvenated and even if I sleep at midnight I still wake up headache-less because of the air.  But then, my credit card's maxed out and have to work overtime again so that I can make up.  Can someone advise me on what to do?
