I don't know where to live

okay so I'm a high school senior right now and after graduation I'm going to be starting barber school. from where I live now, if takes about 30-45 minutes to get there depending on traffic. I'll be going to school Tuesday- Saturday 9-5 which is going to make it difficult to hold a job, if I could have one at all. anyways I'll be 17 when I graduate and won't be 18 until the end of August. I'm currently living with my grandmother, my parents are split and my mamaw's house just always seemed better than living with either one of them. My mamaw started asking me about a month ago where I was going to live. honestly I don't know. I can think of any possible way that I'm going to be able to move out on my own when I more than likely won't even be able to have a job. I love my boyfriend but my family would hate me if I moved in with him out of wedlock and I don't want to be married until after I graduate barber school, God willing that I'm still with him. I just don't know what to do. 😞
