Hi Poet,
I have to agree with Skeezyks on this one. And I know for me, credentials are huge. Also, if you were to see the one at your church, assuming the same boundaries/confidentiality applied, she might actually hinder your growth in your workplace because of those boundaries. Can you seek out this other woman as a friend and mentor, and see a professional therapist separately? I know the drive sucks - but I think long term it would be a much better option.
