I need some advice from a more experienced adult

So I’m 21 and my aunt is giving me her dog grooming business in a year or 2. In the meantime she wants me to go to a pet grooming school that cost 7 thousand dollars and goes mon- fri 8am- 4:30 pm. I currently make just enough money to pay my bills and have some left for food/ gas. My problem is that I wouldn’t be able to work full time while attending the school and when I’m done I won’t be able to pay off the loan until I make more from the business. I don’t know what to do and am feeling overwhelmed just thinking about going into debt. And my bf isn’t much help all he says is that well figure it out. He makes more than me but not enough to cover my bills and his. I only have enough savings to pay for 2 months worth of bills and the class is 4 months.
