Have you gone to the doctor? What is their opinion?
One thing that kind of annoys me about your posts and makes me not want to respond -- not saying I am perfect about this -- is that they are riddled with factual inaccuracies like the following: "I also have a lack of joy and constant emotional numbness meaning less serotonin and dopamine a factor in developing schizophrenia."
You could just be numb because of the dp/dr? The monoamine hypothesis of mood disorders is complete horseshit tbh. Antidepressants increase serotonin in the brain within minutes to hours yet it takes many, many weeks for them to work. Antipsychotics block D2 receptors but dont work for a lot of patients with psychosis. They also dont really treat the cognitive and negative symptoms well.
What is for sure: If your uncle does have schizophrenia, I would definitely not smoke pot again.
