Well I understand your concerns. I thought my past cancer was probably terminal about ten years ago. You have to be there to really, really understand..
Fortunatly I am still here and pretty well. I just consider it free time I should not have had and appreciate it. There were so many things to settle up before the operation and knowing the eventual outcome. I really could not get it all done.
If your intent is to dispose of the car now You are not in the best mental state to do it in. Do you have a close relative or friend that could do this chore for you? You could have them contact me for what to include in the listing if they were unsure. Basically it is lots of good pictures and good descriptions. Plus a reserve you consider fair to you.
I suggest ebay with a fair reserve for top dollar although the need there for top dollar depends on other financial factors present in your family currently.
I always try to stay upbeat and can only state that modern medicine has consistantly gotten better over the years. Your fate may yet hinge on things like the type of cells etc. I am 99.5 percent certain I would not have survived if I had the identical situation twenty five years earlier.
All I can wish you as a stranger is the best of circumstance. This cursed disease attacks one in four of us I understand. I could not easily make an offer for that car myself. I have far too much comprehension of where you are at right now for starters.
Women state all us men are basically all the same.

We also believe to a certain extent the reciprical is true. If this is a given then I found the wifes coping mechanisim to be much better than mine.
Females seem to be more based in reality with serious issues in my opinion. Or fatalistic if you wish. So my wife adopted some kind of stolic approach to the apparent possible outcome. In otherwords what will transpire will transpire. There is really nothing that can change it.
Perhaps even if women are long given the more powerful emotional displays. At a certian point there is a very logical mechanisim that activates in my experience. I have always thought nature gave them a set of switches in their minds we do not have. God help you if you were to accidentally trigger them in other circumstances.
Now the way I might deal with this car issue. Get the car appraised. Take the appraisal to the bank and get a life insured loan on it. Then if you do okay pay the loan off. You will keep the money to do this.
If it goes the other way instruct your wife to get a good friend or relative to ebay the car with a reserve you give instructions about now. One way or another the wife will get a fair return. Depending on financial need perhaps more than otherwise possible.
The way life seems to go you will have to satisfy the loan yourself. If not the concern is covered. I will end by wishing you the best possible outcome. It is strange I can develop the same feelings of empathy with a total stranger I would with a good friend or relative. Maybe there is yet hope for this world.
