Does this sound like schizophrenia? I'm so afraid?

I've been under slot of stress. Whenever I try to lay down,sleep or just close my eyes. I get these racing thoughts of everything I have to do,unwanted thoughts, imagination running wild, sometimes the voices in my head are voices of others who I know or just bad unwanted thoughts. I try to block them out and they won't stop until I want to scream. I just lay there crying because I feel as if I'm losing my mind.
