Ok so I caught Covid anxiety so it has died down but still lingering and rn, I took a melatonin, and my heart just feels like it may stop, I mean I am perfectly healthy I am pretty sure considering I moved around all day just fine, but I am walks scared to sleep now. Idk if I should lean off of melatonin or what Iv taken it for like 4 months now maybe 5 and my heart rate at night feels slower and I just get worried sometimes. It feels like this heavy feeling before I sleep and it feels like my heart is just gonna give up, I’m just scared of it happening and don’t feel like doing this rn, I just wanna sleep but I wanna wake up as well. Can someone tell me, if I have either taken too much melatonin, and I’m only 18 and healthy so my heart wouldn’t just stop for no reason whatsoever right?
