I read my last response and it sounded confusing. I will use an example to illustrate it.

Issue: Detached protector mode is too strong to do anything with.
Goal: To get rid of it and replace with healthy adult mode.
Method: (this is where the therapist comes in)

In the method section, when you get to the stage where the therapist has no idea what to do anymore and has given up, this is where I decide to take control and lead the therapy. I use her as a resource and me as an info source. I look at myself and find out what the problem is (eg. my detached protector mode is nearly invincible). Then i use the resource (therapist who has knowledge of schema therapy) to ask "how can schema therapy assist me to destroy the detached protector?". If i do it in a stepwise, logical manner then it takes the pressure off the therapist and gives me hope for a resolution. If I didn't go to all this effort and just let the chips fall where they may, the therapist terminates therapy after the 4-5 session window because they are just plain out of ideas.

So its not a power thing when i say control, its more of like what i described above. Its like me realising that therapy will end soon so I better make use of this resource before it is gone. If i had money to go therapist shopping, i wouldnt bother with all of this stuff. But when you are on welfare you only have one place you can go to for free therapy and when its gone its gone. So its me just making sure i gave it a good crack before being terminated.
