Maybe try doing nothing. For some people that would drive them crazy, but for others a month of rest and peacefulness can be life-changing. Try turning off the computer for a month. Take walks. Read a book under a tree. Smell the flowers. Meditate.

Also, I'm not sure if this counts as travel, but Shenandoah is only about 1:30 from DC. Getting a small cabin or a room in a bed and breakfast for a month is not so expensive. Immersing yourself in a more natural, less hectic environment can itself be extremely restorative. And you can even sew / embroider while you're doing it.
