Heart scare urgent😨

So right now I’m laying in bed on my phone waiting to get tired to go to sleep, I just started to get tired I minute ago and a minute after (not sure if that matters) my heart just pounded like one beat, if that makes sense. Like it was normal then all of a sudden my heart went BOOM:(boom..boom..boom..BOOM..boom..) I don’t know how else to describe it😬 It was so much it made me sit up as it happened, like I braced myself because it was like WOAH wth. anyway now beside this moment I feel like I’ve had this kind of thing for like the last month maybe more. Or idk, just something weird with my heart. Now, I’m quite a worrier so i don’t know if it’s just something I’m making up in my head...(I know this wasn’t tho, for sure) because a couple months ago i was in the hospital due to a very random episode I had one night where I was shaking, had a shortness of breath, very weak and had a very elevated heart rate. Now that light I was very sleep deprived, I literally stood up the whole night (till 6am but even longer because of the time at the doctors). So they never found out why I had an elevated heart rate they just said a was unique basically..but they did diagnose me with acid reflux which I think I do have (but very little, like not even bad enough for medication in my opinion) and asthma, but I’m pretty sure I don’t have asthma. If anything i might have sleep apnea but that might just me being a worry wort again..ugh..anyway ever since then I have been worrying about my heart. 🛑Now I’ve felt this like pounding heart beat/skipped heart beat feeling before but nothing like this🛑, this was crazy and pretty scary..I should also mention I’m pretty sleep deprived today, I woke up earlier than usual and have been super tired all day but toward the end of the day I start to wake up more. So I won’t be tired but I will still feel like I need sleep, kinda like groggy feeling. I was just now getting tired and then that happened (not sure if that matters) welp idk what this could be or if it’s even normal, ugh but I’m really not sure if I should go to sleep, probably sound silly but I just feel like something might happen in my sleep and then I won’t wake back up or something. 😐(I might be a bit over dramatic but bare with me lol)

((I know this is long sorry))

Update: I will add recently I have been feeling sharp pains and a little bit of throbbing in my chest. 😬
