Hello Amber, I'm sorry you're suffering with paranoid thoughts and fear feelings (also with the hallucinations, as you've described in your other post).
I think you probably know no-one here can diagnose you but what you're experiencing sounds pretty serious and I'd straight out advise you to talk to someone in your life about it, your parents, your doctor, your school counsellor or pastoral carer. You really don't need to suffer like this in silence or alone and I'm not sure this forum can help you as you need helping.
Hope you do decide to speak to someone at home. Best wishes Amber.
