Firstly Stop smoking pot! Speaking from experience that's the only way you're going to get better. Don't do it again and you will recover. I had the same thing happen to me. I had to give up the drugs I was taking. I was heavy pot smoker at the time. i only ever did it every now and then after I got better but each time I did do it I always felt a substle psychosis coming back. So then i nipped in the bud and gave up completely.
Now life is normal again. i have a child 6 yrs later and things are okay.
I'm sorry you're losing your job. just try and recover for now and you'll find work again. Maybe see if you can some valiums or sleeping tablets to help with the anxiety. You know I got off risperadone a couple of months after my psychosis. I didn't like what they were doing to me and my gp totally was against them too (the menatl health clinic prescribed them to me) and so my gp then just prescribed me valiums like I said and temazapams but that was when I could already tell the difference between illusions and reality if that makes sense.
