For me therapy was antithetical to developing autonomy. It encouraged dependency and deference to external authority.

When my T gave me advice about things that might help me move forward, I felt compelled to act on this advice, even though it went against my own sense of whether the things suggested were doable or appropriate (most of which I had already been over in my mind prior to discussing it with her). What was autonomy-building was realizing later that I did not need her advice, and that I already knew what was what.
