Reading through your first post, i couldnt help but say "Im not alone", since im going through more or less the same things you described & yes as a starter i thought my heart is failing and im only 30yrs. So, i went through a complt heart checkups like ECG, ECHO, ETT(Stress Test) & Blood Cholestrol test, everything came back normal. Have been to the ER twice with chest pain & palps, but both times ECG ruled out the heart thing. So, finally went back to doctor with all reports, he suggested checking the blood for thyroid, that im yet to get done. But I posted in Anxiety forum and a friend there has talked about Gall Bladder in reply, and here as i see HappilyWrapped is talking about the samething, this cant be coninc. So next visit to my Doc which i hope i'll do something soon, i'll forsure bring this Gall Bladder topic up and have it checked. Will let you know what happens than.
Meanwhile, quit worrying about your heart, I know i did, and now feel much better, Thanks God i found this place HW, its the greatest thing which could have happened when i was feelin down.
So cheer up, get through the tests and keep us posted, since I MUST KNOW since im going through the same.
God bless you all, and may we all find LASTING HEATLH & PEACE.
