My anxiety attacks from the past few days have really taken a toll on my body. I get nauseous if I'm hungry in the slightest (I did throw up once), and my stomach is on full meltdown mode. My bowels are so upset that I have been defecating mucus. My heart rate has been stuck at at least 100 bpm, and the left side of my chest hurts. I didn't get any sleep last night and I genuinely feel like my anxiety is going to kill me. I'm 19 with no history of heart problems, but I really wonder if I need to go to the ER. I can't keep going like this.
