Budget and income problems are much easier to solve. Plus the skills you need to solve each of these (budget and income) are used throughout your lifetime as your income and budget changes. To change your income - pick up a second job, even part time and it will greatly help. Try Uber or Lyft or something else. I know you are in school but one of the critical skills is learning self reliance. Borrowing additional funds under the Parent Plus loan is not a good idea. You are shifting the responsiblity over to your Mom rather than fixing the debt issue now while it is smaller and easier to handle. Throwing the debt into a student loan is the worst thing to do because now the debt is not dischargeable - which closes off or more accurately, reduces the effectiveness of the Bk option for you if you need it in the future.
Try YNAB to set up a budget.
If you aren't making enough income you only have two options: reduce your expenses and/or increase your income. Once you set up your budget, come back here and let us help you. I still think you can do this without filing Bk - and without borrowing more money.
Keep in mind: You can not borrow your way out of debt.
