Ever since I was 18 I have had healthy anxiety as part of GAD when it’s bad I’ll have a lot of physical symptoms constantly for weeks including heart palpitations, shortness of breath, bloat and huge head fog that intensify with panic, I am having an ECG and bloods for low heart rate next week (only realised the other week but checking my watch it’s been like this since at least 2017) but the spiral begins again where everts sensation cripples me and I’m checking my pulse/ google all day. 

The doctor has prescribed me 50mg of sertraline which I am considering starting.

My question is has anyone else experienced health anxiety like this and using Sertraline to relief the feelings and physical symptoms? 

Thank you in advance.
