weird episode last night

[Mannybilly]

mind before all this happened i had a slight headache that was coming and going, with some muscle tension.i was tensed and upset about a certain situation. anywho as i went to lay down i felt i was smelling something very strange, my head and back muscles were tightening and felt slightly lightheaded, my skin also started to have some sort of reaction. i started feeling nauseous, and like my food come back up. i even felt short of breath. at first i thought it was an allergic reaction, or something serious that i couldn't think of. i ended up vomiting and feeling somewhat better. however i smelled something ammonia like, urine but my mom and brother came into my room and couldn't smell anything, if anything they smelled the food i had ate before bed but nothing like ammonia. im just wondering what this could have been? i was up until 5am trying to relax my body and muscles from being so tensed. i did wake up fine i am tired, im just super concerned because i have no answers. did my stress build my headache into a migraine? did i have an anxiety attack that caused my sense of smell to act weird.? i really have no clue. please give me some answers.
