Aristotle's principle (all things want to return to nature) might be of use.

You have made a declaration because you are frustrated. I believe you desire time alone but your body has a habit of distracting itself with the external world. What you can do is simply go somewhere to go camping or fishing or whatever all by yourself, and simply try not to think about anything at all. Bring a Rosary with you and pray it here and there (this is vital if you're suicidal). Do not take a phone or anything like that... simply go there in isolation where your body "cannot" interrupt that isolation, and clear your mind.

When your mind is clear, you'll be more attuned to what you really want to accomplish in your life, because the desire of your thoughts will begin to overwhelm the desire of your mind, and the desire of your soul will also get louder. It is only then will you know if you truly want to live a "simple life" or if you're merely looking for a break and your body is not letting you have one because you're trapped in a cycle of frustration. (This is easy to fall into when we have phones and internets readily at our fingertips).
