I get anxiety and stressed so much that i make myself sick and can't eat or get diarrhea and nausea. what should i do? :(

Restructure thinking: Anxiety can lead to panic attacks that cause physical responses such as loss of appetite/stomach upset/diarrhea/nausea. Beneficial treatment includes seeing a psychologist to build cognitive skills that restructure your anxious thoughts/thinking through questioning stressful thoughts. Perhaps asking yourself when stressed"Is my thinking working for or against me? Can I view this another way?"
