Drinking epilepsy

Yesterday I had not really nice situation, After leaving the mall I went to the bus stop, when I heard a scream. I turned around and saw the a man who was laying lying in the parking lot. He had convulsions and from his mouth came on an alcoholic liquid (next to him was the bottle) and blood. Lady with dog called the ambulance, and three men took a drunk to the safe place. It's probably stupid, but when this man lay i was thinking what I will do if he stop breathing. I gathered to vomit when I saw him, but I know that he is human and he deserve for first aid like everyone. I feel guilty now. Thats why I must buy a mask with mouthpiece to provide first aid. And what about a man? He got up and finished the drink before the ambulance arrived...

Alcoholic seizure

"I turned around and saw a man lying in the parking lot." The verbs "to lay" and "to lie" are tricky -- even for native English speakers -- but useful to distinguish.  Also "who was" should be omitted because it adds nothing to the meaning.  No need to correct the rest because Brooke and azzipog each did a very good job!  Very nice writing! :)
