You’re just redlining your systems with stress hormones and lack of sleep - your fears have a way of manifesting physiologically when you are in this state (for you schizophrenia or otherwise going crazy) - but you are not. Real “crazy” people don’t mind their delusions and are usually forced into treatment by loved ones. You’ll be okay, the hard part of your situation is going to be not believing your own fears - but I promise once you get your anxiety under control by educating yourself on your own panic cycle your symptoms will lesson, and eventually disappear - though it will take some time because your body takes time to purge itself of the stress hormone generating your symptoms. Anyone would have a difficult time in your situation and it makes sense if you’re prone to anxiety you’re experiencing it intensely now. Take a breath, and lean on your friends (or this community here if you’re short on friends at the moment.) You will be okay, I promise.
