lost on what to do?

ok, so i am already on zoloft (100 mg) and seroquel (seroquel is for sleep, 25 mg). and im thinking of switching to abilify because of my psychosis (i feel like im slowly slipping into an intense truman show delusion + other delusions), but im scared too due to being a system. im already covert, and zoloft makes it INSANELY hard for us to talk to eachother. part of the reason we know we are a system is bc of the intense changing in our wants / needs when we switch and our horrid dissociation, things like that. i dont want abilify (or any antipsychotic) to make things worse for me, but i have no idea what else to do. this has been going on for my whole life (in and out of delusions, which is also worsened because of my dissociation + systemhood so i already feel insanely disconnected from the world in general?) i hope this makes any semblance of sense 😭.
