I really want to go out and live alone for a few days without the control of my family. How should I tell my family that I want to travel?

Just tell your family directly that you are in a bad mood and want to go out to relax. The place you go is safe. I've been in this situation before. I've been out there too. But you’re not far away from home, you can go somewhere closer. Find a few close friends to go with. The family will be very relieved. But tell your family why you want to go out and relax? Why are you in a bad mood?

I think they understand!
