Of course, well-wishers are very important people in our lives. Though talking to them may resolve some issues, there are many limitations. In the busy life of the present, friends and family have their own problems and may not be listening very carefully and unintentionally end up giving advices that may actually prove more harmful than helpful. They may not be able to look at you objectively. They can be biased unconsciously because they have preconceived notions about you. There is a possibility that they can influence you with their personal values and judgments. When issues are complex, they may become anxious and transfer their anxiety to you, whereas a professional assesses you based on scientific knowledge and thus the bias is very minimum and objectivity is very high. A professional will be able to help even if the issue is complex because he is well trained to understand people and possess the skills and qualities to help!
