I'm having separation anxiety that my husband is going on official travel for one month. I've shared with him my childhood traumas, and he's always there to understand and support me. He's leaving his clothing and perfume to me to help comfort me. He also let me know that we'll be calling each other throughout the duration of the trip to keep each other company. However I'm still crying multiple times per night, even when he's at my side comforting me. What should I do?
