I contemplate “running away” all the time, but I’m 23 and I have some money saved up. Sometimes I think there’s nothing holding me back, other than my fear, which is probably true. But I think you’re probably pretty young and all I can tell you is that it’s a hard fucking world out there. Even by the time people are 18, a lot of us aren’t ready to be thrust into all of the responsibility that comes with the age. If you aren’t prepared, just don’t do it. I don’t know what’s making you feel this way, but truly having no one to turn to or rely on is harder than you probably realize. You may already feel like you have no one to rely on, which might be the case, but if you face this world on your own, it’s going to be that much harder if you don’t have enough money to take care of yourself. You have to find inner strength. That’s the only thing it boils down to. Life could very well feel impossibly hard right now, but you will make it through. Once you are at a place in your life where you know that you can safely start over, do it, if you still want to. You’ll also be that much stronger emotionally, which will help you through life more than you know.
