A moth goes to the doctor one night...

A moth goes to the doctor one night. They sit down in an examination room and the moth says "Doc, you gotta help me. I just can't sleep at night."

"You're having trouble falling asleep?" asks the doctor.

"Not just that. I can't sleep at all. I was hoping you'd be able to give me something.

"We'll see," says the doctor. "How long has this been going on?"

"For weeks," says the moth. "I've been having nightmares. When I was in the war I saw the most horrible things. Burning bodies. Dead children. Friends fried right in front of me. It was just terrible, doc. Every night I see their faces staring back at me. And then I feel it."

"Feel what?"

"The pain," says the moth. "I could've done something, but I didn't. And every night it haunts me and never leaves. I wake up screaming, doc. Screaming! My wife can't take it anymore. At first she would hold me close and tell me everything was alright. But now, now she sleeps in another room. She says she just can't do this anymore. Says it's going to hurt the kids. she's going to leave me, doc! I lie awake a lone every night and I see that bug zapper on the house next door, and I think how wonderful it would be if I could just...just end it all." The moth is sobbing at this point. "I can't live like this anymore. I want to sleep! I want my wife back! I want my kids! I WANT TO BE FREE!!!! HELP ME DOC! DO SOMETHING FOR ME PLEASE!!!!!!!"

As the moth rolls onto the floor wailing uncontrollably the doctor says "Moth, that is terrible! This is a very serious problem. You don't need sleep medicine, you need to see a psychologist! You need help! I'm sorry but I'm just not proficient in that field! Why did you come here of all places so late night anyway?!"

"Well," says the moth, sniffing. "Your light was on."
