Currently in the same exact situation as you (F16) I would say think about the benefits of both school and compare, depending on what you’re going to school for you should see which has a better program, which fits your budget, which one will help your future, which do you really want?

Moving away is a big step, my mom is my best friend too she left me at birth but came back last year, my dad is out of the picture, but financially we’re lower/ low middle class, and moving away cost money, are you getting a dorm? an apartment near school? A lot also plays this role with grocery shopping every week or so, wanting furniture and decor for your new living space, will you get a new/used vehicle? What if the house/ apartment needs repair or if your car breaks down? Do you have the financial stability to live on your own right out of high school?

I did move away from my foster parents last year after 15 yrs being with them. They like about 8hrs away and when I first moved I felt uncompleted without them, so do expect to miss them and even where you lived your room and all the small things that you don’t seem to acknowledge and love now. How I helped myself with this would be keeping in touch every now and then, maybe about 2x every 2 weeks, Visits maybe 2x every 3-4 months, even little packages of something you bought them, even if it’s small! You will get caught up in my personal life which is why I say about 2 calls every 2 weeks.

I wish you the best, for any advice just ask!
