The worst year of my life

My mum was diagnosed with Stage 4 ovarian cancer in August 2024. Sadly my dad lost his battle with skin cancer last week, being an only child I am terrified of now losing my mum too. She was in hospital all last week (while dad was in a hospice and passed away, she wasn't well enough to visit him. It has been the worst year of my life.

She was in hospital because she has been extremely nauseous after her 6th and last chemo session in middle of Jan. (she did not suffer with sickness the whole time she was on chemo - only since finishing.) Her Oncologist told us the last 3 chemo sessions had been ineffective and so were going to try and move her onto a different chemo drug. However now she has been unable to hold in fluids & food she has become incredibly weak and they have said not strong enough to start this new chemo. 

She has tried basically every single anti sickness medication there is and nothing worked so we called an ambulance and into hospital she went. After having a tube down her nose to stop the vomiting and drip set up to get fluids in via canular they managed to get the sickness under control. All this while I was having to sort my Father being taken to a hospice. 

She got out of hospital on Friday - on Sunday evening the sickness came back.. I had hoped and prayed she was going to get her strength back enough to start more chemo but now I am absolutely terrified that I am going to lose her! 

She had a Stoma fitted in August when she was diagnosed but has not had surgery to remove her ovaries. They have said that due to the spread they do not think surgery will be of benefit. 

Is this the end? What more can I do, I feel utterly helpless and broken.
