I just bought a heart rate monitor. I did it because I (36F) have a pacemaker and constantly worry that it is malfunctioning or that the battery is dying prematurely. I am hoping that it will ease my mind some. I am conflicted because I know that I am going to obsess over my pulse. Constantly checking it when I feel fatigued or not "right". By having it, I hope to be able to show myself that it is still working properly. I won't know for sure if it will help, but I hope it does. I really don't want to live the rest of my days scared and worrying over my impending death. I hope I made a good decision. 🤷‍♀️
