I wouldn’t say you have “no adult experience” but you’re in the beginning entering the thick of it. There is more to adult experience than finances but those situations will present themselves to you when time comes and you’ll have tools to use. Ive been on my own 19 and have had absolutely 0 family support. I would’ve wished people were kind to me and helpful when I was your age. If you need help on anything, don’t hesitate to ask me.
