I am so tired of being sick and tired. Sometimes I am so weak I think I am going to pass out. My heart beats out of my chest. I sweat and freak out. The nausea is overwhelming. My head is spinning and I am lightheaded. I keep thinking I have to be sick with a disease since I feel sooooooooo bad. Has anyone felt this ill with anxiety? Does anyone feel sick, sick, sick? Is a sickness making me freak out or am I feeling sick because I am freaking out. I can't take one more day.
