The thought process of a panic attack versus a stimulant overdose.

The snowball thought cycle of a panic attack:

"Oh shit I overdosed."
"I'm going to die a worthless meth tweaker."
"I should go to the hospital"
"No, I can't, everyone will know. They might call the cops."
"I hate meth. I should have never done that."
"I'm never taking this drug again."
"Oh my god my heart is going to explode."
"Please, someone, save me. Give me another chance. I'll be good. I'll change."
"It's going to happen at any moment. It's going to happen. It's going to happen."
"It'll be painful and no one will help me. I will die."
"What happens after death?"
"I don't want to die."
"I just want a second chance."

Thought process of a real overdose:

"What the fuck is wrong with me?"
"I'm shaking uncontrollably."
"My kidneys HURT."
"My mouth tastes funny. Like metal or pennies."
"I can barely move."
"My heart is out of control. 200 BPM? That's not normal, I took the bump 10 minutes ago."
"I'm so fucking hot. I feel like I have a horrible fever."
"I don't care if the cops get called or my family knows about my use. Take me. Call 9-11."
