Psychiatric evaluation is based on history, clinical symptoms, personality factors, ongoing psychosocial stressors and frequency and severity of symptoms. It requires direct interaction with the patient on a regular basis. Once diagnosed, a management plan is formed based on intensity and frequency of symptoms and associated biological and psycho social factors. A complete solution to ones problems in a single question is thus not possible. Internet will give you generalised tips and tricks but they are hardly of any use. I suggest you to visit a psychiatrist in your vicinity for clinical evaluation.
