I get that Luckygirl, I have the same. and had what you are suffering many many times. Remember, this WILL NOT kill you!!
If you’re unsure and scared, don’t forget you can always call an ambulance. I’m not saying exaggerate your symptoms but don’t play it down either.
If you call an ambulance, they are very thorough, ECG, blood pressure everything. If they think it’s dodgy, they take you in, if it’s ‘just’every day AF, they’ll leave you at home. Even that comforted me, knowing i was medically stable even though i didn’t feel it!!
Best of luck, and don’t hesitate to message me if you need more chat/ support.
