Flow is a state of non-resistance, of being in the heart, of fully accepting both stillness and movement, whichever is being supported at any given time. It is allowing your beingness to lead the way. It is replacing struggle with faith, trust, comfort, and support.
If you are uncomfortable, explore what you are resistant to. Is it the now moment? What if it is serving you in some way? Is it the future? The past? Yourself? How can you move into non-resistance, and then into acceptance?
Use your body as an indicator. You will feel a lot of tension in your body when you are in resistance. What allows that tension to diminish? Make it your mission to find ways that work for you. How can you get out of your mind and into your heart?
It may be finding an activity you like. It may be prayer. It may be meditation. It may be nature. It may be exploring or trying new things. Experiment.
