My experience that the SW and OT will just say wait for a crisis. It is very hard to leave yp Mum as she is getting you on side with the neediness. My Mum was very controlling and could get aggressive. I used an advocate to to write to Mums GP explaining the situation. I visited Mum when I could but I always took someone with me to support me as I was very wary of the situation. Yes definitely they wont provide help for your Mum until you leave your Mum on her own. At some point you will reach your limit and wont be able to help Mum. Canary is spot on, My Mum could not cope even with carers coming in 4 times daily. You have a choice. Talk it over with the SW and see what they say. If they have discharged her, talk to your GP.
