New-ish diagnosis that i don’t believe

I’m new to this group. I was diagnosed with paranoid schizophrenia in 2021 because I expressed to my (ex) psychiatrist that i thought people were following me places and i’d get scared thinking they were going to kill me (ex: driving on the interstate/highway), always looking around scared someone is gonna make a move and shoot me, as a kid i would hear faint screaming of multiple people, & one time in the bathroom back in 2019 i was using the bathroom and all of a sudden heard a ton of whispering voices out of no where which lead to a panic attack because i had no idea where they came from. I don’t hear anything like that anymore. but now im more scared of ordering doordash in fear they are going to poison my food, remember my address and kill me, or im scared family are plotting against me to be some bad person when im not, or i would get scared that my mom was going to kill me (she’s a little crazy tho) and was plotting to kill me. I get so scared that i start to imagine these scenarios in my head and i become scared of this person for awhile until it eventually goes away. so yes, im a paranoid person, but is it really paranoid schizophrenia?

I am also diagnosed with Bipolar 2 Disorder, major depression disorder, generalized anxiety disorder, panic disorder, & borderline personality disorder.

I have been on one antipsychotic (abilify) and it made me hallucinate demon looking things and i never took it again.

im having a hard time accepting this diagnosis because i feel like its not paranoid schizophrenia but maybe some other paranoid disorder.
