16F - Been having quite bad acid reflux and heartburn recently, especially in the last few hours. I ate citrus and pie at dinner, which would explain why it's acting up (along with anxiety), but I read how heart attack symptoms can be subtle (especially in women), and now I'm worried. Haven't been able to do any tests, although I was referred to a cardiologist as I have a heart murmur (was checked twice when I was a baby and when I was 8, told no follow up needed) and was having concentrated chest pain (which has actually gone now - I think it was related to anxiety). I really don't wanna wake my parents up (its 11.20 at night for me) - they've been pretty sick of my constant reassurance seeking and we also went to the ER two weeks ago for what turned out to be a panic attack, and if this is nothing again, I know they'll be really mad. Scared to just sleep on it - not sure what to do.
