Your concern and caring come through in what you wrote. Your father is lucky to have you. Do you have specific concerns about any of the symptoms? Palliative care can be very helpful, and I hope it is proving useful. Do you feel your dad is hoping to stay alive for a specific event or to see a particular person? Or for more time in general? You don't say if there are other caregivers supporting him. But having been a caregiver in several situations I just want to also encourage you to take care of yourself, and rest too when needed.
