So this all started a couple days ago when I made a vow to exercise more as I dont work and I noticed after a very long walk my heart was over 100 bpm for hours after, after looking into it more o found out that it's most likely a combination of being unhealthy and anxiety but I have made an doc appointment for tuesday just in case.

Anyway since then I have been obsessing over my pulse and everything my heart does and I have had sleepless nights because my heart will get down to 55- 60 bpm wheb I'm tired and about to sleep which i read is to slow.

I'm 18m average weight  but inactive I've read your heart only goes below 60 if your an athlete so this has really been worrying me at nights to the point I only get couple hours of sleep.

Does anyone know if this is normal and has anyone got any tips on to stop focusing so much on my heart.
