Well I've had one of those fortnights...2 weekends ago I was on my own as my partner was traveling for work and I developed a tooth abscess. It was one of the most painful things I've ever had. I ended up having an emergency root canal. I was a bit shocked and extremely tired due to lack of sleep and my chest tightened the minute I sat in the dentists chair. now 2 weeks later, I'm on antibiotics, and now full of cold with aching body and stuffy nose/head. All simple things but my health anxiety is trying its best to raise its head. I keep getting little chest flutters and that horrible feeling of doom but, I'm ignoring it. I'm going to make myself a cup of tea, read, and relax. It's such a bugger sometimes but I think you just have to acknowledge it's there and get on with your day.
