Undiagnosed and scared

Im undiagnosed rn but schizophrenia runs in my family,my brother is paranoid schizophrenic and my dad was as well. I've been experiencing heavy delusions for about a year that have been getting progressively worse for about 3 years(just recently getting very bad). I've also been having memory loss. Im really really scared. Like really scared. I watched my brother and father go through this and it did not end up well for them. Just would like some advice please. I plan on getting help with my next check btw. The delusions run my entire life and i feel like im scaring people around me or making them think im whacked out on drugs
