Well, none of it is ideal, whether we're talking about psychology or psychiatry; but some people do have verifiable imbalances in neurotransmitter activity in the brain. Drug treatment can help those imbalances.
Far better though, is Christian fellowship, prayer, and service. It gets one's mind off oneself and onto God and one's neighbor. And let's be frank: many people who have "psychological" problems got that way because of years of selfish behavior. Especially illicit drug-abuse---hard drugs and alcohol. Dealing with substance dependence and eliminating it is over half the battle with many folks.
So, I would say: 1) Christianity first. 2) Prescription meds. only if medically indicated because of a chemical imbalance. And then MAYBE 3) some short-term cognitive-behavioral therapy with a Christian counselor to address some specific habits.
Psychoanalysis is garbage. It won't help anyone is any practical way, IMO.
The whole Psychology/Psychiatry thing has gone too far---Ritalin for children; long-term therapy which does absolutely nothing, etc. It's terrible. People should be encouraged to put Christ first and then work hard in a Christ-like way for others. That is the best way to preserve mental health.
