Generally speaking, online psychological counseling can only answer the confusion of visitors according to their written descriptions, and can simply give suggestions for general psychological problems, but it cannot be used as a standard for clinical diagnosis, and it is difficult for counselors to grasp the root causes of psychological problems. In addition, excellent and experienced psychological counselors in various psychological counseling rooms generally do not appear on the Internet to help visitors solve their psychological problems, unless otherwise specified. In addition, psychological counseling pays attention to finding the causes of psychological problems from all aspects. Therefore, in face-to-face psychological consultation, the counselor will trace back to the root of psychological problems through communication with visitors, with the help of their pronunciation, intonation, mental state and behavior, while the psychologist has the right to prescribe and prescribe corresponding drug-assisted treatment as appropriate, which is not available in online psychological consultation. In a word, the diagnosis of online psychological counseling will have great deviation, so it has not been really recognized in medicine at present. Network psychological counseling can only be regarded as a way for psychological counseling institutions to serve the public at most.
