Should I go far away?

Think more about what you want to do. I think a year's travel can change you a lot, and at your mother's age, you shouldn't need to take care of yourself. Your mother is actually the happiest. If you don't do what you want, you can only do less in the future. Besides, I think this kind of thing is actually very simple. If you communicate with your mother, she will understand you and envy you for traveling far away.
