I'm really anxious at the moment. I am convinced something bad is going to happen, and I've just forgotten what it is. Makes me feel the same as exams coming up or some scary social situation. Just now my chest suddenly closed up and it got hard to breathe fully. Does anyone else get this? Randomly it feels like something is squeezing my upper chest, so I can breathe but never take in a full breath. It's not asthma or an actual sickness, it's more like pressure.
