My aunt is giving my sister/me to start fresh!

This is the second time I’ve asked this group. I’m sorry. I’ve been offered by my aunt to live with her 13hrs away from my hometown bc my mom’s going through a mental breakdown.. she said she’ll help us go to back to school or get a job. My sister and me pay rent at our mom’s house but will lose the house if we move 13hrs away! I want to take the opportunity to better my life but my sister doesn’t! She won’t take one of us.. I would be losing the most I have 3 vehicle I paid for myself and a great job in my hometown. My sister only works weekends and got her car from our mother! I think she just scared to change! I hate waiting when we could leave the Jan 1st…. Ik my sister she wait until the last second to make a decision. I have a lot I need to sell if we move 13hrs away!
