@goosegoose - as others have said, you don't need to believe in EMDR for it to work. What your therapist may have been aiming to say is that you need to be willing to go through the process - so, "buy-in" as "I'm going to do my best to stay in the process, not try and keep one foot out and one foot in".
I'd say this is progress. What would happen if you challenged yourself to share more about it, in session?I've been trying to engage in DBT for the last 6 ish months, with "little to no progress" as my T just said today. I partly disagree, because I've really been practicing taking full breaths through out the day, I haven't self harmed at all, and I've even noticed that when I rub my tongue over my teeth - I'm about to split (borderline) and I've even been working on stopping that behavior all together with good progress. I do all my homework like a good noodle but I really struggle to share it with her in session.
I hate to be that person, but...how do you know that you can't do this? (This being, open up and move forward at a reasonable pace). What evidence do you have, that this will take you five years or more, to accomplish this?I've been trying to explain to her that I take a ridiculous amount of time to open up, move forward, etc, but she's really wanting me to consider EMDR. I sarcastically said "what, and then come back to you in 5 years?" and she made it clear that she thought it would take way less time than that for me which is...just not factual in any facet of my life.
