I usually know my triggers but today I just stumbled upon it and now wave after wave of anxiety is hitting me. It's 5am and I didn't sleep. At least I don't have any appointments throughout the day. 
My heart is beating fast and I can barely breath. I tried breathing exercises and took some medicine to calm down. I have a strange feeling in my legs. My thoughts keep racing. Nothing helps. I just want to sleep it through but I can't.
