Lung cancer

My mum was diagnosed with incurable lung cancer in August and given less than a year to live. I've been her carer since then as I live at home with her. Last night was really bad and today the dr came. As from tomorrow morning she will have a carer come in 3times a day. This is to help relieve me from it all. My sister thinks she's not going to last long now. I feel numb with it all and just deal with it on a daily basis. I'm just trying to get through it and not read too much into it. What will be will be. I will be homeless once my mum goes,as we rent our house privately and I cant afford the rent and bills. I cant seem to cry about any of it. I feel if I start I wont stop. My health is not good either,I'm  waiting for a colonoscopy as they found blood in my stools. I should of been having it tomorrow but with mum taking a turn for the worse I cancelled it to deal with her issues. I just feel overwhelmed by it all. Cheryl x
