I, for one, would not ever 'think I've majored in medicine', nor do I think that others on this forum think that way.
When we post on this site we do it not only to get rid of our frustrations, but to possibly help others in their journey and to get the support that so many caregivers need to go through the day to day things such as changing bandages, flushing ports or picc lines, administering antibotics, being an advocate for the patient, encouraging our loved ones to eat, drink fluids, take them to/from their never ending appointments with doctors, oncologists, interventional radiologists for chemo, ctscans, emergency rooms, etc....
I also would not trade one day of Tom's illness because "For Better or Worse, in sickness and health" means a lot to both of us. I know that he would have been there for me if it were he that was the caregiver.
Why do I do it? I do it out of love. Do I get frustrated? Yes. Do I get emotional? Yes. Anyone would, even you have to have experienced those feelings while you were caring for Wayne.
Perhaps you could benefit from counseling to help you through what I can only imagine has to be very long empty days without your soulmate, along with your grief and sadness. That has to be overwhelming for you. You are correct, there is no "I" in 'We'. That has to be hard, to loose your soulmate after being his caregiver for such a long time.
And I know that one day I will be in the same position as you, Darla, Lainy and so many others on this forum who were the caretakers for their loved one. You are not alone here, none of us are alone in this journey. And that is why so many of us have joined this site, for the caring, compassion and love of others who are experiencing the same journey that so many have undertaken, and that so many have 'lost'.
My heart goes out to each and every one of 'us' who have lost a loved one to CC, or to any other disease.
My thoughts and prayers are with you.
