Not the same, too hard to tell, but I can give some of my story that might help...
I started acting strangely around 20. Always had been a little "touched", but things became really absurd around that time. It wasn't just voices in my head, I was hearing things that were not real, seeing things that were not there, and experiencing sensations that made no sense like traveling multiple time pathways and feeling gravity shift from down to perpendicular to me, etc... It was frightening, and I didn't have insurance so I never went to the doctor.
So I went from straight edge to drinking, and then it became a way to cope. This lead further down the rabbit hole.
8 years later, I was homeless, strung out on drugs and alcohol, huge criminal record, suicidal, ruined every relationship, and just.... gone. In and out of jail and court, same deal for institutions. It wasn't uncommon to be walking along, talking to people that I thought were my dead friends come back to life, only to find out that it was a street sign, window, or stranger. Or have street signs change in front of my eyes. Or get helplessly lost all over the place. Didn't matter if I was on substances or not: I was fucked up.
Just over a year ago, I finally ended up seeing a doctor. Found out I'm schizophrenic. Was given medications. Got into inpatient to make certain I didn't use drugs during that time. About 60 days later, everything changed.
The voices were murmurs, the agitation, irritability, and paranoia had diminished. I no longer hurt myself. I wasn't controlled anymore. I had lucidity. My eyes played fewer tricks on me. Gravity stayed down. I stopped having delusions.
Just over a year later, my life has changed to something I never thought possible. I'm sober for over a year, went from 120 pounds to 165, no longer in late stage alcoholism (was bleeding from esophagus all the time, kidneys and liver fucked)...
