My mother has T4 Lung Cancer. I'm caring for her at home but it's hard. Love her so much but need some advice

Hi iv just bn told my mum has Lung Cancer T4 I'm really struggling at the moment and feel like I cant breathe.

I've had nearly a month in & out of hospital been awful .She is adamant she is not going back in so I'm caring for her at her home .She refused carers in but iv said i need them to help me so come morn & teatime .Iv bn staying overnight for weeks but i can not sleep at all with the oxygen tank noise & sleeping on a sofa so i crumbled yesterday had to come home to my bed & home .Still waiting on the key safe & pendant to wear if its an emergency .

She is wanting me at her home all day & I cant, this is not at the stage where pain relief and sleeping all the time & not eating is.

Just need some advice, love her so much but it's hard at the minute.

Any advice would be helpful

Thank you
