Hi there ali,
I think you need to speak with your healthcare professional be that your GP or a care team. Taking a larger dose of antipsychotic medication is not going to make it go away (that's not how they work).
I'm sorry that you're in such distress at the moment, have you tried talking out loud to yourself that you're going to be ok when the voices are loud?
The hallucinations sound scary. I would recommend that you speak with someone about your symptoms if they're getting worse, especially if they are putting you at risk (which it sounds like it might).
It's great that you're reaching out. I would sincerely recommend talking with someone about what's happening and maybe getting out to meet a friend for a coffee as the distraction might ease your symptoms a little.
Take care of you.
