Worried about mum's health

Today was a good day I had a fun time with my sister and her partner, daughter and my mum at her house, then we went to have Chinese at a restaurant called happy meal. Well anyway I went down back to my uncle's place which is near my mum's and in conversation I said to mum that I was concerned about her waking up so late and she replied so arrogantly to me. She said I was going to go to hell and her brother rebutted in to tell her off he's like is that how you talk to people like calm down. Now I just feel like why do I even bother telling her that I'm concerned about her sleeping until 2pm eating her first meal at that time. Like if I care I just get verbally abused for it so why do I even bother if she wants to kill herself slowly by eating late that's her problem I'm not going to bring it up to her anymore. She always says it's because she does so much because she doesn't sleep. Well I've explained to her that she doesn't sleep because she's gotten to this routine of waking up at 2pm so her body is not going to be tired until 4am but she's stubborn. I'm not going to worry about it tbh. Honestly it's not a problem as long as she takes me to tafe there is no direct bus to Rockingham Tafe so she'll have to take me. I don't drive either because of add so I wouldn't risk everyone's life on the road. Anyway it's just annoying when your concerned about someone's health and then they just reply so rude to you. Like that sucks genuinely.

I'm sorry that happened to you.
