This covid thing definitely started mine off and I was in bed for 2 weeks straight. Like you, every symptom of anxiety under the book. Seems I'm left with this. Just hope it goes soon but I need to accept it as anxiety and that's something I really am struggling with as it feels like I cant breath and my throat is swelling all the time. I think it's a similar thing with palpitations. If you look back at my threads, I had them terribly 3 years ago. Once I accepted (after several ecgs, an echo and counselling) that they were benign they went away. I still get the occasional one but they don't bother me. I've even had them mid exercise and shrugged them off. When I first had then I thought every one would kill me. And I had to give birth with them (literally every third beat) while they were at their worst! I really didn't think my heart would cope. I suppose I need to get to that level of acceptance again but struggling when the gp won't even examine me x
