Growing up and moving out on your own is probably one of the biggest shockers you can experience in life, and we're sorry to report that it doesn't get much easier as time goes on. Even nearing age 30, most of us still don't know what we want to be when we grow up. If only they'd teach you practical advice about all of this in school! Alas...
We don't have much more advice to offer you, so godspeed to you on this unfortunate lifelong adulting journey.
