Struggling with DBT Therapy

I feel so lost, been in DBT a little over a couple months and started really struggling the last few weeks when I had a really horrible week and all of the skills stopped working for me. The therapist leading it basically told me it doesn’t seem like I’m convinced it will work for me and it doesn’t unless you’re 100% convinced and committed. I explained I was until the bottom fell out and all the work and skills just stopped working. She is stumped and saying this is the first time she has experienced this in her career. That it won’t work unless I’m confident in the process, and that if I’m not I need to find something else for me. She doesn’t know what that is but she somehow expects me to know. Which feels strange, I’m not a professional in the field so I am not sure what that is, because other people recommended DBT so how am I supposed to know what that other thing is? Really frustrated, upset, and sad
