I'm so sorry it's been such a hard year for you
About the only thing I can suggest to you is to sit down with your vet and ask a lot of questions. You might want to ask about the cost of a scope and flush. If the bleeding is due to a foreign object, that may dislodge it. But if your vet feels it's more likely to be cancer instead of a foreign body, and she's 14, probably the treatments wouldn't give her a lot more time, anyway.
You should also ask about the signs of discomfort and have a plan for treating that if she needs it. Some pain meds aren't very expensive and they can be instrumental in giving your girl good quality of life. Cool compresses on the top of the snout can help stop a nose bleed.
My heart aches for you, hotdiggitydog5.
Cherish every moment you have with your girl and give her a big hug from me, k?
