Yeah, I mean you can't take anyone for granted except your parents ig. It's not like they were bad friends but suddenly disappearing and ghosting your friends is bad for you and people who know you. It's not that they didn't call or mail me, but they are also human beings they also have their own life going on and they can't be thinking about you all the time they have to let go at some moment of time. If you want to do it just don't go vanish in a day take your time, prepare yourself, solitude can be very challenging, you never know when you could need help.
