I am sorry about your difficult situation. I can see why it is difficult for you to trust someone at this time. Delusions and hallucinations feel completely real to those who are experiencing them, even though they are not at all real.
The latter point is important for you to focus on: Delusions and hallucinations feel completely real but they are not real at all. You can trust doctors. Doctors want to help. The children outside your door are not evil. The difficulty is that the sick brain cannot distinguish between what is real and what is not real. That is why it is essential that you seek help immediately.
By not seeking help, the children may be in danger. Please consider going to the doctor or the hospital, despite your fears. I understand how difficult that may be but you must seek help for the sake of innocent others.
Your brain won’t let you know what is real during a delusional period. Delusions attempt to fool you. Never forget this, violence is always wrong. If you feel the urge to do anything that is harmful to yourself or to another, immediately get help. Help is just one phone call away. Dial 911. Help, and I mean real help, will be at your door minutes later.
I hope that you will seek the help that you need and deserve. Please take care.
