Over the past weeks I'd gotten a lot better at sleeping, I've slept at less irregular hours and even slept for longer periods of time than I used to. My health anxiety was less severe too.
Tonight however I find myself unable to fall into a comfortable sleep. I keep feeling like my heart is beating too hard or racing, but when I check my pulse, it's perfectly normal. I cannot stop my mind from imagining my heart going berserk in my chest and stopping altogether. When I'm about to fall asleep I jolt awake, my heart actually throbbing. I keep having these unhealthy thoughts of death and how much I fear it.
There's no other physical "symptom" , no pain or numbness, simply just my anxious mind thinking there must be something wrong with my heart. Even though I recently went for a checkup specifically for my heart and everything came back normal.
I keep telling myself that my body is healthy and there cannot possibly be anything wrong with it. But my mind won't stop, like I have no control over my own thoughts anymore.
I'm afraid and I feel like I'm going mad. It's 02:35 now and I don't see any chance of a good night's sleep.
Has anyone experienced something like this?
