As I began reading your post, I rhetorically asked myself, "Did I write this?"

I, too, am old. Yes, I'm even broke, isolated, obese, pre-diabetic, and habitually sleep-deprived. I can't even remember when I last had love in my life.

Well, sleep-deprived is my own choosing. I just don't want to sleep because it pisses away my remaining hours of life. My body, though, accommodates me by getting me very sleepy so I'll stop what I'm doing (if appropriate) and climb into my very, very, very wonderful bed (alone). My bottom sheet is a fur blanket that is soooo soft. My top blanket is thick, soft fur. My air conditioner keeps me cool under all that insulation. And, (please skip this mental visual part), I sleep naked so I can feel all that fur. Gawd, it's awesome. But... I sleep for an hour and then I'm wide awake. I get about 5 or 6 hours per 24 hour period but it doesn't match the day/night schedule the planet keeps.

I am retired. And THAT gives me one helluva lot to live for. Believe me. Broke, yes. But I live within my means. My rent and utilities are paid for, I gave up my car and leased aircraft, and my sailboat is probably going to be sold later this winter. But, I'm happy. I go for walks, bike riding, sailing and the occasional (gotta do it) flight around Ontario.

I have 7,000 movies of which I've got about 2,000 I haven't seen yet. I play music along with the stuff I've got on my computer (25,000 songs or so).

I have a thousand hand tools to fix broken things that I find.

My imaginary lovers keep me very happy but I worry that my stamina is dwindling due to my age. I am married and have a girlfriend but no sex to speak of because, well, I have my little imaginary lovers. I just keep my real-life girls happy by fixing things, doing errands and the like. They seems to be as happy with me as I am happy with them.

I can't find a single reason to keep on living. Who the hell would fucking care, anyway?

I fucking care, RedViolin. The simple fact that you are hurting makes me care about you. So, I wrote the above about me in hopes that you can see the possibilities available to you. Sure, you might not be happy working on a sailboat and sailing it about the local waters, but you can find SOMETHING to entertain you. Heck, you can even plan an ʎɹǝqqoɹ ʞuɐq ʎɹɐuᴉƃɐɯᴉ or calculate the square root of pi. Or, you can carve a little girl out of granite and place her in your town square. (Take pictures of it before they smash it.)

Don't drive your car off a cliff. The actual fall won't kill you but the sudden stop will. The time it takes to get to that sudden stop will give you lots of time to re-think your intent... which you won't be able to undo.

Death is final. Despite what the masses say, there isn't anything once death is accomplished. So, struggle to find something to put into your remaining life until death comes for you on its own. If you still can't find something, then let the actual search for something be something!

There is nothing wrong with selling your TV and microwave, sitting on the town corner pan-handling for money enough to get an airplane ticket to Antarctica and go there, find a couple penguins to adopt, and take care of them.

Whatever, RV... Don't quit. Nevertheless, if you feel you just MUST, do it in as creative and fun way as you can. For me, I hope my way to exit is just after an intense orgasm.
