Hallucinations of any sort have got to be a mental health disorder that can come from a physical illnesses of any source. They can be accompanied by extreme anxiety but nothing stops them. But it would be good to have a diagnosis of what's going on with you.
How do i handle hallucinations without medical help? I don't want anyone to see how crazy I am. Is it possible to do this?
The only way people won't notice how crazy you are is if the hallucinations stop, and the only way that'll happen is if you get medical help. A doctor won't ever judge you - they are there to help.
