I need advice: the psychosis is already bad, he keeps telling me to kill myself but will it get worse if I keep not taking my meds??

I’ve been on meds for a couple years now, I technically have psychosis but that’s much less well known in the auditory and visual hallucination community basically. 

Backstory: I started seeing a guy in high school (he doesn’t have a name btw but I don’t think he deserves one, I just call him ‘him’) and it took me a couple years to come out with it because of how scared I was. He told me they would send me away from my family if I told people. The main things he would say and the paranoid thoughts I’d get would be my parents were drugging me (giving me mania medication to idk sedate and eventually lead me to kill myself) and that my dad was coming into my room at night and r@ping me. Later on when I told my (depression) therapist he put me on the antipsychotics quite a high dosage, he said if I’m experiencing a visual like ‘him’ as clearly I was I was pretty much bound to have deeper psychosis at a later age. 

After a couple suicide attempts (some before I told about the psychosis and most after due to psychotic episodes) I was put on a higher dosage and I was gonna lead up to the dosage they actually wanted me on, adding more every week.  

FYI: even with the meds he’s always there he just doesn’t speak. 

I basically went to university and was discharged from CAHMS and I’m currently waiting for a proper therapist. Which means the upping of the olanzapine was put on hold idk why my PATH team are fucking shite. 

While I’ve been put on hold, I’ve had multiple psychotic episodes and while this has happened ‘him’ has told me to stop taking my medication so I did. 

It’s about a week later and already my episodes are fucking horrible. He’s telling me to kill myself or self harm (which I have done to shut him up) I was very close to suicide tonight but my brother called me (we call each other pretty much every other day) and I was crying and about to kill myself but he saved me and talked to me for a couple hours to stop me. 

My question is: Will the psychotic episodes get worse if I carry on stop taking meds?? Will it get as bad as like I believe he’s a real person because I’ve honestly addressees him in front of my friends already (accidentally but still) 

Please help it’s only cause my brother  is checking up on my every couple of hours I don’t know what to do.
