My advice is figure this out for yourself. I'm not trying to be an asshole, but these sort of things are big decisions that only you can make. Don't play dumb, you know what going to school can do for you and what going to work instead can do for you. You know what the living situations will be like and who you'll be living with in either situation. Don't make a decision based on what others tell you, because then if you feel like you've f*cked up further down the line you'll look back and blame them instead of looking at the real problem.
List the pros and cons for each side and decide which list holds more weight.
Hell, go and flip a coin for it. Not to actually listen to it, but I can tell you that, for that split second while the coin's spinning in mid air, you'll know which result you want to see.
I'm not really good in this but you should stay with your mom and go to school regularly. You're too young to go to work and earn money so I'd advise you to stay in your home. Don't miss your school life, bro. But, as Rob said, you're the only one who can make the right decision. Just do what you think is right. Good luck.
