Man, what you're saying sounds exactly like Jeff. His was High grade urothelial carcinoma, very aggressive as well. They don't like using contrast dye if the kidneys are weak. Chemo and dye affect the creatinine levels, which I'm sure you already know. Jeff had to have a chemo treatment rescheduled for a week later because his level was too high. I truly pray she doesn't go down the same path as Jeff, but if she does just do your best to keep her comfortable and let her know it's okay to go when the time comes. I should have known that last good day Jeff had (3 days before he died) was a sign but instead I had hope that he was going to make it a little longer. Maybe even until his birthday which would be next week or even to see our newest grandson who will be here in December. I was overly hopeful but in my heart I knew it wasn't going to happen. Just glad my daughter got here in time to see him before he left us. I don't know what I would have without my kids and rest of my family. My sister was by side 24/7 it seemed like. She went to dr appts with me to be my second set of ears since she has been a surgery tech forever. I'm an MA in cardiology so oncology is a foreign thing to me and I really wanted no part of it.
Jeff was greatly confused and I attributed it to the meds. Then later I think part of it may have been a stroke.
You will go through many phases, so angry is ok and good to let it out. Keeping it in doesn't do you any good.
I agree no one should have to endure this and I don't understand it either. Don't be afraid to ask the dr for something to help YOU. I had to do that and trust me I needed it, I don't think I would've made it without it to keep my anxiety down. As always, still here for the venting. Let me know how her treatment goes.
