I'm so stressed, I'm suffering from constant hallucinations.
Really? That sounds very serious, have you seen a doctor?
No I haven't. The hallucinations are getting worse.
Having hallucinations is a big deal. You should definitely see a medical professional about this as soon as you can.
I'm not sure who to call about this.
Talk to your primary care doctor and they can refer you. If you don't have a regular doctor, go to urgent care and they can refer you. You need to take care of this as soon as possible.
