Hello! I’m new too – I’m so sorry about your mum.
My advice to you is to call your mums doctor and ask to speak to them. Explain that you know that they cannot tell you anything about your mum, but that you need to make them aware of her current condition.
Insist you need to speak to her GP. You really need to make it clear that you are asking for their advice on what you can do for her. That way, they are then aware of how serious its become and they will be able to tell you how to get the support you so clearly need – and maybe arrange a home visit so they can see her condition for themselves. It takes the weight off your shoulders, you should not be having to deal with this.
Your story is so similar to mine, except it’s my husband in your mum’s condition. (heavy drinker – 30 – 40 cans of lager a day, constant vomiting, not eating and muscle wastage, loss of bladder and bowel)
I’m sending a big hug to you and lots of love.
