I'd like to start off by saying that i'm 17 and male. Last night I was just watching youtube when all of the sudden everything changed. In a split second I went from happy/giggly to a full on throwing up, sweating, shaking, disorienting attack. I can't identify why this happened but it happened around 9PM last night and it's been 25 hours and I got some sleep because I took some Promethazine (couldn't stop throwing up) but I feel very weak, my head is in a completely different spot, and I haven't been able to drink/eat much if at all. What could be causing this? I still have this tightness in my chest along with an intense anxiety feeling and I woke up in a panic attack this morning but since then I've been able to keep it under control but I am still shaking and it's almost rehabilitating. I'm already on anxiety medication (Prozac + Gabapentin)
