I hope you are aware clarity, that among the physicians who are here, I've yet to notice any post they made that included a diagnosis. If you are truly concerned, you should probably see a doctor.
That said, within this forum you will find some personal accounts of individuals who have gone through the experience of psychosis and/or schizophrenia. It may be helpful to read through them -- if you are having similar experiences I would suggest that you seek out the professional caregiver of your choice.
if you are not having similar experiences it will still be worthwhile to examine your drug use. Some studies have linked schizophrenia with marijuana useage, and both mushrooms and LSD are hallucinogenic drugs that are known to produce altered states of consciousness.
If you are using these drugs as part of a spiritual path I suggest you consider a less harmful practice such as meditation, drumming, or chanting. I also suggest you explore the links between drug use and psychosis so you can make a thoroughly informed decision before continuing with your experimentation for whatever purpose.
You may further find it beneficial to read a little bit about both Isaiah and Michael. Drug use played a role in their experiences
Dedication.
As a belated PS: Your brother might enjoy my blog:
Spiritual Recovery. It's devoted to the subject of recovery from psychosis and/or schizophrenia. You'll find it linked in my signature.
