Okay so I'm 18 going on 19, and I've had anxiety since around age 13-14. When I was younger, I started experiences episodes where I'd become paranoid that members of my family were psychopaths who wanted to murder me and that they were trying to poison me. These episodes were usually short (a few minutes to a few hours) and were not so strong that I couldn't differentiate them from reality (kind of like OCD rituals for me). I had one such incident a year ago, but that was very minor to the extent that I was able to eat the food and got over my anxiety.

Outside of that, I experience generalized anxiety (health, social, family health) and more paranoia. Examples of paranoia would be worrying that someone in my family has cancer but is keeping it from me, worrying that I have cancer but am not being told, being suspicious of cars parked nearby, being scared that a car is following me or that someone nearby at night is (but again able to shake that feeling off), and probably some other things that I can't recall.

It's happened mostly equally throughout the years but maybe a bit less in the past year or so with only my depression being worse in the past year but not exceptionally bad. I wasn't worried about it until I mentioned it off-handedly to someone and they freaked out about those things be warning signs for schizophrenia.

Are these warning signs, or is this something related to my OCD &amp; Anxiety?
