While I have not been in this position myself, I watched my wife leave a high profile corporate job. She needed a period just like you are describing where she did various things to mentally prepare for the next chapter in her life.

She also had to figure out what business she will start, you already know what your business will be, but still have to face the challenges of growing it in a challenging environment.

Take time to decompress, put your life and mind in order and when you are ready you will succeed in growing your business.
