I am a 20y/o man, with a few chronic illnesses. Tonight, my chest hurts (aching/dull) and feels like a huge weight is sitting on my chest. I also feel weak, shaky, and dizzy. I have long-qt, which has caused me to pass out before, but it didn't feel like this. I am functional enough to speak, sit up/ walk slowly on my own, etc, but I can't focus enough to read and I feel like I'm going to fall asleep with how tired I am. Should I go to the ER?
