Struggling with Dissociation in Therapy

**Prossible Trigger Warning** I'm on my 3rd therapist, the one that diagnosed me, and I just dont know what to do. I feel like my symptoms are "too bad" for them to treat. I know that can't be the case. I can't be the worst they've dealt with... and if I am what does that say about me? What does that mean for my recovery? I think this because of the ways they respond not because I think I'm worse than anyone. I'm always dissociated. Sometimes its worse than others, my lips go numb and I can barely even hear myself talk, but even when it's not that bad it's still painful knowing I'm on autopilot. Knowing I'm missing out on my life, on my daughters life. She deserves better, my husband deserves better but I'm not able to "wake up". DBT is even difficult because I can't think clearly, my consciousness is so blurry its hard to learn and use dbt skills. Is this level of dissociation common? If so how do you cope? What therapy are you trying? Do you have any advice at all? If its not common should I look into dissociative disorders?
