Okay So I'm Not Sure Exactly What It Is So

Okay so I'm not sure exactly what it is so I will list what has happened.
-earlier a fly flew in my nose or mouth, I think mouth but other things make me think otherwise.
-felt something in ear, probably fly going out, I'm not sure.
-saw a fly, I think I same, I got rid of it.
-I was fine until I felt a spike feeling in my thoat
-I now feel a heartbeat (in throat) and I can't tell if I feel blood running there or it's just me over thinking, panicking etc.
-also a few minutes ago I had some chest pain and have recently suffered from chest, abdominal pains and headaches.
-I currently also have stomach growling sounds which are probably unreal ting but I occasionally get other sounds like popping there..
-I have a headache near the back of my head too.

I am 15 and I think I may have anxiety, it's 3:52am and I have no where of going somewhere, if I say something to my parents they will probably think I'm just imagining or overthinking things.

I know it's a lot but I panic a lot and just want to know what's wrong with me.
