Is Johnny really suicidal?

In Chapter 3, Johnny and Ponyboy are lying on their backs watching the stars. Johnny is smoking a cigarette and says that Cherry was embarrassed to be seen with them because they were Greasers. Johnny then tells Ponyboy that he can't take it anymore and says, "I'll kill myself or something" (Hinton 47). Ponyboy is alarmed at Johnny's comment and tells him that he can't kill himself. Johnny says that he won't and comments that he has to do something about it. He tells Ponyboy that he wishes he could go to a place where there are no Socs or Greasers, and everyone is ordinary. Based off of Johnny's comments, I do not think that he is suicidal, but I do think that he should speak to a therapist. Johnny clearly has personal issues and is lacking a supportive family. His environment is not conducive to a prosperous future, and he needs to leave the city. Although his friends are genuine, they participate in illegal activities which only increase Johnny's stress. Johnny is not totally disillusioned with his situation yet, which is why I believe that he is not suicidal.
