If you have been diagnosed with psychosis
by a doctor, then it is good news that you are able to realise that you have psychosis.......which shows that you are regaining that touch with reality....the most important aspect that is lost in psychosis. That means almost half of the battle is won already for you. Good luck,
If, on the other hand, you have diagnosed yourself with psychosis or your family members have done that, then there is a good chance that you might not be psychotic at all since you accept the diagnosis of psychosis and hence you have that touch with reality.
Since you talk about voice experiences, then there is a need for you to have a full psychiatric assessment, if not had one already. This will help to find out if this psychosis is due to sever depression
or due to any other problem. The treatment is dependant on the label that can be given to the "group of all symptoms" (syndrome) that you are experiencing but the commonest denominator in all problems is treatment with antypsychotics.
The various methods of distraction that you can use will also depend on the severity of the voice experiences. Distraction helps in mild-moderate cases but not in severe cases. The best way to get rid of voice experiences is to use medication along with eradication of the cause of psychosis, if any, like treating depression with antidepressants, stopping drinking if the voices occur due to this, stop taking drugs if this is what is causing it etc..................so again you need a psychiatric help.
If you are already using medication and the voice experiences are persisting, then you need to contact your doctor again to optimised your treatment. You could also use talking therapies like CBT which may help in you adjusting to the voice experiences. Medication is the only treatment that I know can help you get rid of the problem.
Hope this helps.
