The previous research describes creative writing to have a potential for self‐care and healing in relation to illness and mental health conditions. The aim of this article was to deepen the understanding of creative writing and human becoming, from a caring science perspective. A data material consisting of answers from an e‐form and diaries was analysed with a thematic analysis. The result depicts two main themes and seven subthemes. The first main theme, Creative writing – an act of emotional reactions and release, shows that creative writing is an act where fears and emotional reactions are unveiled; it is a relieving valve for the writer and includes moments of liberating wordplay. The second main theme, Creative writing – a key to self‐understanding and personal growth, shows that creative writing is a genuine conveying of oneself to others, to experience mercifulness within oneself, to keep up faith in oneself and hope for the future and to find a new order of values. Creative writing enhances human becoming and gives possibilities for human beings to find inner peace and balance in life.
