…that's it really.
I suffer anxiety generally, had depression a few years ago.
Recently suffered bouts of raised heart rate and general tight, achy chest and have been referred by GP for echo and 24 hour ecg.
I know it's probably the anxiety but I've convinced myself I'll have a heart attack/fall ill on holiday. 
I'm not on any meds for it, generally controlled it with exercise, diet, quiet life etc.
Feeling awful and panicky. Would really rather not go.
