Reading/Numbers/Processing with Psychotic Symptoms

Hi, so this is pretty much self-explanatory

I'm 18 now (yayy) female in uni undiagnosed. I've been on abilify for like not even a month now at a low dose

and to preface this, it may be completely normal--i have literally no idea what is/isnt a normal thought or thought process to have but i may just be a hypochondriac

I feel like I have noticed a mental decline since maybe 8th grade. I went through a lot of trauma in high school (freshman and sophomore year) before switching to homeschooling where I found myself better fitted than public high school (where I was generally bullied/struggling with home issues and attendance)

Now, over the last two years or so I have realized i keep misreading numbers. I will misread them multiple times, and attempt the problem, get it incorrect and check the blackboard only to see the number I wrote down was completely wrong.

I mentioned this to my therapist and he suggested dyscalculia but to my understanding that isnt a visual thing, its a processing issue (i have done very minimal research lol) and this isnt something i remember having in school so it would be acquired dyscalculia (which is typically from a brain injury or some kind which ive not had) but seems apparently sort of common in schizophrenics from one study ive seen (im almost certainly not schizophrenic)

additionally my spelling and vocabulary has declined

I find myself making more errors, forgetting words, making grammar mistakes, making spelling mistakes (suddenly ive been misspelling words for my entire life, or misusing them and somehow never realized or was told) despite always doing excellently in english as a subject (720 on the sat english section, 2nd place in spelling bee in 8th grade lol, high reading level, etc).

I think i tend towards attempting to connect everything in my life to my psychotic symptoms but an ex of mine (who was schizoaffective) told me that kind of thing was also very common amongst schizos in general. I have not had anything back this up (google, therapy etc). Just wanted to see if this was a common experience! thank you guys
