Anyone seeking therapy is ready for therapy, it depends on the type of therapy.
Initially, it may simply be supportive therapy, for instance, is most appropriate. Just an example.
If I am a therapist and I have just paid for-- invested time, money and energy in a specific modality -- I need practice (practicum) hours and I need to pay for my training. I may fail my client by thinking my newest area of training ( and my practicum hour needs) fits my client's needs, when it's a disaster waiting to happen, especially in the field of trauma. Most trauma clients cannot afford these types of mistakes.
Gus raises a great point. Sometimes trauma clears when the time is best.
I am also with the Skeez (?sp) on "Compassionate Abiding."
I tend to think our systems know when to allow enough to surface and how to clear traumas. Wild animals face trauma, often daily, and clear it. I feel a lot of mistakes are being made in trying to find artificial methods of clearing. sometimes mankind meddles too much in things which occur just fine naturally.
While I may be "uncomfortable" while trauma resolves, isn't the discomfort a natural consequence of the trauma? Discomfort isn't "bad" and may not need to be changed, other than how we think about it. We truly benefit from self-compassion, being mindful of our own needs and maintaining patience.
Journaling, in my opinion and experience, is a great idea. You can always decide if you want to share it all. or not, and when.
