anxious about the future

Hi! My brother (late 20's) got back from the ward, he's in his final days of getting outpatient treatment. And then... I don't know? The docs seem to think he's quite functional, I agree. Everyone wants him to work, mostly because any job gives structure and a balanced schedule. He hasn't had a job since summer. In his psychosis he left home, lived out of the car, and spent his days going round and round the neigbourhood. He's med compliant, but I'm so afraid he'll come back to his old ways. I should be okay and happy we got him back, but all I do is having these awful scenarios playing out in my head
