Hi everyone. I'm here out of desperation. I take some heavy medication every day, one being Seroquel. This pretty much keeps my anxiety and panic at a manageable level. My body has become reliant on this medication to sleep. I unfortunately forgot to pack it when i went away last night. Last night was okay except i literally did not sleep once even though i was exhausted. So now i am home, I've taken my pills, and my body is seriously needing sleep. The pills also make me extra drowsy. 

Now whenever i start to drift off into sleep, i get an intense wave of anxiety that feels like a mini panic attack that lasts for a few seconds. This has happened over and over for the past few hours and it's driving me insane as i just cannot fall asleep, and every time i almost do, that wave of anxiety, heart palpitations, chest pains, etc hits me. I don't know what to do or why it's happening? What is this and does it go away?
