I was about to sleep an hour ago... But then i woke up after 15 minutes.... My heart rate is racing... I can feel each and every heartbeat... I feel like I need to puke and I also feel hungry... I feel like I can't breathe properly(it feels heavy).. I feel like I want to cry too .. man this sucks so much /: I just wanted to sleep... Now I am scared to go back to sleep cause of this... All of sudden I'm scared that I will die in my sleep. 

I’ve had this so much before I don’t understand it fully but I think it’s just ocd 

Omg I get that too. I have so much anxiety I dont get much sleep and Im constantly tired. Im sorry you are experiencing that

Worst part is that u aren't experiencing or feeling the anxiety. And it hit u once u go to sleep
