While I understand your concern about psychology, if you have read and listened to Dr. Michael Horton, you would probably realize that he believes that the Bible is the ultimate counseling book.
When Dr. Horton says "... while we oppose the 'end-run' around the cross that psychology often performs when it assures non-believers that God is on good terms with them, we do not condemn psychology itself, only its attempt to usurp the place of God. Psychology is a very helpful and necessary tool when used wisely"
He is not saying that all psychology is helpful, he is saying that it is helpful when used wisely.
The key word here is "wisely".
The word psychology is not a bad word in itself. Just like the word theology is not wrong. Unbiblical psychology is wrong; psychology that is biblically based is helpful.<br>Wrong theology, such as Arminian theology is heretical, but Calvinist theology, is biblical.

Proverbs 11:14 says "Where no council is, the people fall: but in the multitude of councillors there is safety."

I have met a lot of Christians over the years, who although they definitely are believers, they still have mental scars from past and present circumstances.
Being a Christian does not make one immune to this. However, it can help when someone comes along side that person and councils that person. It doesn't have to be a professional. But that councilor/s should know what is good and what is bad advice.

Perhaps you are unconvinced concerning Dr. Michael Horton; if that is the case it would be best to contact him yourself. At least that way you would know one way or another.
