Ok, circular logic, I kinda see your point however you can't just sit and expect God to deliver an answer. When literally there is the internet and FREE help available by trained professionals to guide and direct. Of course a Christian should also pray and seek God's help, but just like the man who was in a hurricane and died, he asked "God why didn't you save me.." God replied, "I sent you a boat, a helicopter, and the Coast Guard... "
You are assuming the person taking the counseling will trust the counsellor and that is basically putting your bad experience onto theirs which is unique to them. Kinda like how your experience is unique to you. It's not about knowing God more than the other person, its about accepting that they can provide answers and help faster and with more experience to back it than you have.
Do you do your own dental work, or do you see a dentist when you have a cavity? The same applies here, and mores she has the ability to test what the counsellor says against the word of God, and to pray about what is said. This isn't taking away God's authority at all, it is simply working together to achieve a common goal. That is to heal, recover, and move on from the trauma in order to step out into a new life.
I mean, isn't that what we want? Jesus didn't heal the demonic possessed man just for the man to sit there idly... He told him to go home. When people saw him, they were astounded by the change in him, and the man testified that it was because of Jesus.
