There is no “one size fits all” for therapy – some clients do experience considerable shifts in a brief amount of time with IFS. There are also clients who experienced more complex, difficult events in their lives and take a while more to find enough regulation and reorganizing in their system.
You can decide on the frequency of the sessions based on your expectations of your therapeutic journey, the changes you notice between sessions, and resources available to you. Similarly, you are also free to terminate the counselling arrangement at any point, although a closure session to round up the therapy is recommended. Feel free to talk to me about what may be suitable.
