You mention no sign of of psychosis which would involve hallucinations, and delusions etc. You have been in therapy, but the type of therapy is most important.
I would recommend the use of Cognitive Behavioral Therapy. In CBT, one is taught new ways of thinking and behaving and as a result, one's mood improves. anxiety attacks decrease. In addition CBT is evidenced based as the most effective form of treating anxiety. See:
Incidentally, for therapist to label a patient a sinner is most unprofessional. I wish you luck and hope you do not give up on treatment.
