Delusions?

I need some advice about paranoid delusions. I have been in an unstable situation since May 2023 with what my psychiatrist has put down as paranoid delusions.

For context I had a heavy cocaine addiction between the ages of 16 - 22 years old. The use stopped at that age, but I still have the addiction. I have been married for 19 years and have three children under 13 years old. Back in 2022 I began to suspect that my wife was using, it seemed she was able to control her usage and it wasn’t interfering in her life. In May of 2023 some things I discovered at home, with further digging into her phone and apps, her behavior and health, and based on my previous experience as a user who funded his habit doing not so kosher things that she was finding her habit through dealing/distribution.

I had some form of breakdown following this and over the passed two and a half years I haven’t been able to shake the conclusion I came to, in fact her behavior and the characteristics of cocaine use have continued to worsen.

My question is that based on circumstantial evidence and filling the gaps in with my own experience I came to a conclusion, the psychiatrists I have seen have said that it is a delusion/hallucination! -Does anyone have experience of a long term delusion? -Also, there are times when I have extreme anxiety from this and end up in hospital, I am calm and back to normal with 24 hours of being away from her and my home environment, is this a typical recovery time for anxiety from paranoid delusions?

• what’s the difference between a delusion and jumping to a conclusion?
• I have had neuropsychological tests and they came back with ADHD and Autism level 1, with no psychiatric condition
• When I go to hospital they say it’s Schizophrenia and I am medicated with Risperdone. I feel like I either have some version of Schizophrenia or am being gaslighted.
• Two things can be true at the same time too. I have an underlying condition and she could be also doing the things I concluded she was too.
