CBT (Cognitive Behaviour Therapy), I've always considered something for milder to moderate issues including anxiety.  Whilst I feel it has its place in therapy, I think it needs to be delivered by a qualified specialist therapist for those of us which are at the major/severe end of the 'scale'.

"Cognitive behaviour therapy is a talking therapy that looks at the connections between our emotions, thoughts and behaviours within the context of specific circumstances and symptoms."

There are people, who are really stuck.  And if you can't express your emotions, thoughts and behaviours then it's really difficult to get anywhere.  I also believe any form of therapy needs to be particular for those of us with PTSD or related conditions.  Once you start asking about emotions, thoughts and behaviours that involve flashbacks then a therapist is really treading on thin ice.

As it's a new psychologist, I'm not sure if it's your first psychologist.  My experience has been that a good psychologist will assess their new patient/client because really they don't know what has happened to their new patient or how volatile or vulnerable they are.  CBT is one treatment, most psychologists (and psychiatrists and other professionals) use multiple treatments so often you can choose what works best for you.  Perhaps CBT is your psychologist's main treatment.

I would ask what treatments or modalities your psychologist works with, and if they have some reading material to help you decide what may benefit you.  I would want to know what else is an option to try, how long they've been a psychologist for and if they would discuss your treatment with your referring GP (should you want this done).  It's ideal if your Doctor is in contact with your Psychologist, but this has to be your consent to do.

You may read information on CBT and feel it's not for you.  For me, Mindfulness generally spooks me so I avoid it.  It sounds to me like your negativity is a loud voice?  Maybe you'll find after a few more sessions that you and your psychologist have a better idea of where therapy will lead and perhaps starting on that negativity will be beneficial.  Negativity is a stubborn thing to shift, but not impossible.

Not only do you have to find a therapist that suits you, but the therapist needs to connect with you as a patient.  Such a match can take a while.  Read up on what treatments he/she offers, and pace yourself.  Give both of you some sessions and time to build a connection.  I wish you well.
