Do you think I'll be alright on my own?

I'm 23 and moving out in two weeks, I will be living with a roommate in an apartment. I'm excited and know it's time for me to go, but I can't help but feel a little nervous/sad about going. When I was 18 I moved out to go to college and I moved back home within the first month. This time I feel different and feel like I am mature enough to go out on my own plus I'll have my own room/bathroom. I'll be 15 mins from my moms house as well. Will I be ok? Any advice?
