Yes this is the beauty of it, you can absolutely come back to the journal, and refresh your memory, redo the therapy, the prompts, re-read it. Whatever you need!
It is natural to have moments of doubt, or even forgetting how far you've come, maybe your ex has got in touch and you are considering going back into that relationship.
This is where the journal is great, as you have a log of everything. Nicely organised to help you make an informed choice or simply re-gain clarity.
Come back to the journal to remind yourself, what you have endured, your progress, and to keep your strong mindset refreshed in moments of doubt.
You can return to the journal as many times as you need to !
