My 7 years old son suffered separation anxiety issues when he started going to new big school after a long gap of two years due to pandemic. He doesn't want to study ,not to go to school, dislike school, vomittited daily morning 3_4 times while going to school, sometimes has headache, stomachache, leg pain .crying, sad always, all started from july when he started going to school. Now he is having panic or aggressive attacks , behaving aggressively at home, crying, and showing tantrums. Psychologist suggest. Lonazep md 0.25 mg tab 1/2 three times. If no medicine given started behaving aggressively n angrily. If we didn't sent him schools quite normal for long time .how long should I give him medicine. 25 days over still no improvement .he hated school. No issues in school , teachers are good and supportive. He want to be at home only .coz the past two years he was at home fully .please suggest what should I do.
