I will start by saying I have several health issues - Addison’s disease, asthma, kidney issues (recurrent chronic utis), and hypothyroidism.
I found out my mum has terminal cancer recently.
Around this time my health has taken a massive nose dive and I’m struggling. I went to the doctors and they did two ecgs as I was having palpitations. Both of them came back as showing I have an enlarged heart.
What the actual fuck?! 
I have now been referred to cardiology and I can’t seem to get any straight answers from anyone if I should be worrying or not!!
I am now in a massive panic thinking there’s something seriously wrong with my heart and I’m going to die 

My gp wasn’t very reassuring and just said matter of factly she’ll be referring me to cardiology because I’m a “very complicated” woman so it needs checking...
Any words of wisdom!!? Seriously freaking out, which I know isn’t going to help.
