Hi, I posted here before about the same type of thing. I'm 17 and have very bad health anxiety. I know I have anxiety but am still convinced im dying. For some reason I focus everything on my heart. I'm 100% convinced I'll die young from cardiac arrest. I've been to countless doctors. Had 8 ekgs an echo and just got my heart monitor off yesterday. Aside from the monitor everything else keeps coming back perfectly fine. I get my holter monitor results tomorrow.
I've worried about this before but it really started up bad again about two days ago. My heart rate was at 51 BPM while I was trying to sleep and would go no higher than 70. I thought maybe it was because I recently started lexapro 3 days before that. When my mom called the on call doctor at my pediatrician he said to watch it and if it stays low to take me to children's. Well I flipped out and we ended up going where they found nothing wrong but some mild dehydration again.
This is a never ending cycle with me and I'm absolutely lost. I feel weak and shaky everyday and can't eat right. I don't sleep normal. I'm just convinced I'll die young and the cause will be cardiac arrest. I have no clue what to do and wonder if other people have this.
