Good that you have survived from the struggles and difficulties of finishing your studies due to financial problems, money is not everything but it can make you happy. Try to pamper your parents as this is the best time to return their kindness of going through a lot of struggle to help you finish your studies to become an engineer then help others who are struggling from financial problems but still very determined to finish their studies. You were once upon a time in their shoes so you know how it feels when somebody is giving you a hand so you can survive :) cheers.
