Hey all! This is my first time posting here in years. I suffered from health anxiety about 5 years ago and it was a daily battle and took over my life for quite some time. I went to therapy and also put on meds, and one day I just overcame it. For the past 3 weeks it came back and my anxiety has been through the roof. I'm 28 years old and I lost 70lbs in the last 20 months. This was a complete lifestyle change and I work out everyday for a half an hour and I also completed my first half marathon so I was running a lot. The last 5 days my heart rate has been in the 50s, and when I'm sleeping drops down to like 46. When I didnt have anxiety and things were great it was in the 60s and dropping down to the 50s when I was sleeping, occasionally 48. I've been freaking out about my HR and that I'm just going to suddenly die from it. I have a drs appointment next week and I'm scared something terrible is going to happen before then. I need some reassurance before I go crazy!
