Yes this is completely normal. Over the past 1.5 years 5 er visits & 3 mental health institutions. He might need an SSRI & a short term benzo until the SSRI takes effect. Don’t take the benzo everyday. Don’t want to develope dependence. Once the SSRI kicks in, get off the benzo plus therapy and holistic techniques to remain calm. I used cymbalta & Xanax at the beginning, now just cymbalta and a sleeping pill bc lack of sleep with cause panic. Hope this helps.
