I know it sucks, but I agree you did the right thing by going back. Even if you can't think about it being best for yourself to be in hospital right now, does it help to think of how worried and scared your mum and Jasmine would have been if you ran away, and/or of how much extra work and liability that would have been for staff in both wards/hospitals? It wouldn't have just gotten you into trouble and in an unsafe situation. It would have put a lot of other folks in a bad situation too.
I hope things improve for you soon. Thinking of you.
