Should I move back?

I’m from Metro Atlanta and I’m interested in moving to Jacksonville, specifically looking around the Mandarin area. I have lived in Florida before, in late 2019 my dad moved the family to St Augustine only to die a year later during the pandemic. A year after that, my mom made me go back to Atlanta with her. What I was able to experience in that roughly 2 year window I really liked and I know for sure I like that area. I love Florida as a whole. Why Jacksonville instead of St Augustine? Well because it’s not as expensive, because this time on my own. My mom is hoarding dad’s money until she dies. I know a lot of people like to riff on Jax, but that’s more like just making fun of your hometown in a joking way or understandable criticism of something that needs improvement. I don’t have any connections in my hometown of Atlanta besides mom, and she’s gonna cut me out her life for abandoning, possibly forever. I’m really nervous and I want to know if I’m doing the right thing or if it’s just a waste of time and money (that I’ll have to spend on rent instead of living with mom).
