If you do decide to lead a nomad life then you must explain, to the people you love and to the people who love you, why you are leaving. To just up and leave without a goodbye or an explanation would be cruel, people love you and they need to know what is happening to you. If you can handle the explanations and goodbyes then you may well find what you need from the nomad life. If you just up and leave, then whatever you are running away from will stay with you and haunt you in some form or another.

Good luck with your choice.
