Several things come to mind with what you have related.
Firstly I agree with
@Tinyflame - if it's anxiety it needs treatment because it's not being managed well enough right now.
But of course you have to ascertain whether or not it
is anxiety or your heart. That's a big problem if nobody is listening or wanting to investigate.
An ECG and a decent physician should be able to do some tests to eliminate most heart conditions.
So absolutely you must follow through with these investigations. If you have these symptoms you must eliminate all physical causes - especially the big ones like heart conditions.
I wanted to comment on your use of Xanax to treat anxiety/panic. I used it for a while and I know it's hard to believe but it was the reason I began to feel sick. I was having palpitations, feeling nausea and other symptoms, all easily attributable to heart conditions too. I ended up in emergency one night because the pain was quite severe & I was convinced it was my heart.
After my psydoc became aware of my admission he told me that in the absence of a diagnosed heart condition he suspected Xanax. I hardly could believe him but I really did want to start feeling better asap so I stopped taking it on his recommendation.
I was taking 1 mg per day... a incredibly small dose compared to what some people are taking. But I tossed them and I felt like crap for about three weeks but the chest pains subsided without any medical intervention as did the palpitations and other symptoms.
So, I can say without doubt it was the Xanax and there seems to be a fair bit of noise about it creating more problems than it fixes. So it's definitely not a drug to dismiss when you start feeling unwell and please don't take a double dose.
I know how terrible you can feel with the out of control anxiety/panic - it's truly horrible and quite believable that you do think it is your heart. The only things I can suggest are be very aware of your current environment and shut it down if there is too much going on. Reduce stimuli, practice anything that is calming and rest. It will subside - all on it's own if you give it a good chance.
Best of luck for tomorrow. I hope it's not your heart. Let us know. :hug:
