I never heard of the concept of attachment until I came to this forum, and I've had years of therapy under multiple therapists, so it is definitely not the focus of every therapist or everyone's therapy. I worked well with my therapists and my therapy was very helpful. We had healthy therapy relationships. Is that attachment? Probably "secure," but it doesn't really matter to me so long as my therapy was helpful for me.

Give yourself time. Don't compare your therapy to anyone else's, particularly on here. One of the dangers of reading therapy forums is that some start doubting their own therapy or thinking something is missing or wrong in their own therapy, and they start second-guessing things. What matters is what is going on in your own therapy with your own therapist. You problems being able to trust are normal under the circumstances. Just stay focused on you.
