Dude, take your medications. If you don't, you'll end up having another psychotic break. There is hope though. As long as you stay away from hard drugs, a few puffs of cannabis a day shouldn't set off another psychotic break. Some rules- eat well, sleep well, take you meds, and stay off hard drugs. Use marijuana very sparingly. You'll lower your tolerance and you'll find that a little bit can go a long way. The most important thing is to stay on your meds. I can't stress that enough. Only you'll know when the onset of a psychosis is upon you, but everyone else will see the actual symptoms when it's too late. If you find that marijuana starts to make you excessively paranoid or manic, switch strains. But please, start taking you meds again.
