Don’t ever run away,unless your parents physically hurt you or they threaten to kill you. Then you need to call the police. Get help.
Stay with a relative, an older sibling, an Aunt, a Grandmother…etc.
But Never run to a different country. You will find yourself in very harmful and hard circumstances.
And Don’t depend on anyone, such as an “internet love” who promises you a life of bliss. NO. If that’s the case, think if they are so great, then why aren’t they having a g/f (b/f) where they are already? And if they “love” you, they will wait for you when you’re old enough.
Don’t run. There are laws to protect you. Use the law. :)
