My lovely little sister (age 22) is having a severe psychotic episode, seemingly out of nowhere. I'm currently looking after her 1-year-old DS (who is delightful, and seems happy to be here with his cousins, although obviously he must miss his mum). She was sectioned 4 weeks ago and there's still no improvement. Is this an unusually long time to be psychotic? Will she get better? I hate that she's suffering this, I feel so worried for her DS, and, on a selfish note, I miss her so much.
