My 12 year older Jack Russell has Lymphoma, she has been having Chemo for around 2 months, she has had her good days and bad days, but more recently she has been really ill. For a round a week she has had really bad diarrhoea and sickness and hasn't eaten for a week. She has been staying at the vets all day for 4 days hooked up to IV antibiotics, she was really sad and down and the vet says we may need to talk about putting her to sleep if she doesn't improve, since then she has perked up a bit and started eating again and seems better, not fully herself though. Tomorrow is the day where he will run her bloods and then advise me if she is better. During the chemo journey I made a promise that I would not keep her alive if she is suffering, I constantly worry over her and it's making me really sad, I had no idea it was going to be like this, I was really positive. At this point it's not the cancer that's making her sick, as it's gone, it's the affects of the chemo and her immune system, as it's low due to the chemo, so she is prone to pick up more illnesses. But we cannot stop the chemo as the cancer will return. Seeing her this week has made me realise that we maybe coming to the end and I can't stop crying, I have tried my best and I can't enjoy life as I'm constantly worried about her, it's like a dark cloud hanging over me. Not sure what I am asking really, just a handhold and maybe some good advice. There is a small part of me that is hoping her bloods have improved and she will be ok again.
