Uh yeah, so I guess it started like... maybe last week? Or the week before. I've had this kind of weird pressure thing in my chest, like not pain exactly, but like... heavy? Especially after I eat, or sometimes when I'm walking uphill. I thought maybe it was just, like, acid or something 'cause I get that sometimes, but this felt different. Also I've been more tired than usual, like even when I sleep okay, I just feel drained. And once or twice I felt a little lightheaded when I stood up too fast, but that could just be me not drinking enough water or something.
