The cbt therapist should be able to give you the tools you need, it is then up to you to use them correctly. At the moment you don't have the tools which is why you're struggling. Imagine you're rewiring a plug but you're using a knife instead of a screwdriver. You're not going to get very far! Your therapist has a screwdriver. She could do the plug for you but then you'd have to call up everytime you needed a plug doing. Or she could give you the screwdriver and let you get on with it.
