I need reassurance Please!

Hello,
I'm new to this website and this is my first time posting. I have been diagnosed with PTSD, OCD, Depression, and Anxiety. I know I'm a hypochondriac. Well three weeks ago I started to hear what sounded like whispers out of nowhere. I don't think I hear them anymore but I am not sure because I mostly hear them when I'm alone or in a noisy room and I have been around people lately. I'm still not sure if it was white noise from heaters/fans etc because I did hear it more when I'm around that. I did go to 3 different therapists from the same practice 3 different times because I thought I was going schizophrenic and all three times they assured me that I wasn't and it was my anxiety. Despite this, I am still so scared of developing schizophrenia. I don't want to go crazy and I don't want to loose my family and boyfriend. I keep picturing ghosts, the devil, scary stuff to make myself feel schizophrenic and I'm so stressed that my mind actually falls for this stuff. I sometimes feel scared of something and in my mind I say leave me alone. I also think about scary stuff like what if they misdiagnosed me and I have early symptoms of schizophrenia and I will get the actual disease later in life. My parents aren't schizophrenic, nor my grand parents, or my aunts and uncles. My brother was misdiagnosed with schizophrenia bc he was also hearing voices along time ago but not anymore. He is fine now just depressed. I'm paranoid I always ask ppl if they hear or see certainn stuff and they do. I'm scared of being alone bc I don't want to turn schizophrenic with no one watching me and I think if I do ill kill myself because I would be crazy. I know I don't have it but I'm trying to convince myself that I do and I'm already accepting that I will eventually have it. please give me some words of encouragement. this has also made me depressed everyday I don't want to do anything. I dropped out of my class this semester in college. I don't work

Sweetie you're not going to turn schizophrenic. And I think you'd already have a history of behavior. I had extended family that was schizophrenic. I don't think you are.

You want reassurance, but reassurance is very temporary. At some point you'll need to face down these frightening thoughts about being schizophrenic. If it were me I'd tell myself Oh Well If I Get It, I Get It, and move on. I have to do that sort of thing all the time with OCD.
