When we are in thought, we are also creating a sense of isolation as we are in there on our own! This is why it can literally feel like the walls are closing in.
Taking your senses outside, listening, feeling, smelling, as well as seeing, can really change your experience to one of calm, joy, connectedness and mostly ALIVENESS!
Being PRESENT is what feels ALIVE and the way to truly experience wholeness.
Do something for yourself each day. Venture outside!
