I am fully functional thanks to THC.
One study, even if it's from Nature, cannot by itself prove anything.
First sentence:
Cannabis use increases rates of psychotic relapse and treatment failure in schizophrenia patients.
Second...
Clinical studies suggest that cannabis use reduces the efficacy of antipsychotic drugs

The present study demonstrates that exposure to the principal phytocannabinoid, Δ9-tetrahydrocannabinol (THC), reverses the neurobehavioral effects of the antipsychotic drug risperidone in mic
So, yes, they combat each other in effects. But that doesn't at all mean THC is healthful. In fact, it is likely the surest way of being forcefully medicated with antipsychotics. It's not going to recover one from psychosis.
The study was about a psychiatric theory. For those with psychosis including past weed use, try antipsychotics with this particular mechanism, and THC has the opposite effect.
The mechanism/substances:
non-P-gp substrate antipsychotic drugs
If you are "fully functional thanks to THC", you're a very, very rare case. And I am really, really skeptical about you claiming that....
