Good physical health. I've been plagued for the last 20 years with a debilitating chronic illness that has made my life absolutely miserable and not worth living. I've missed all of life's milestones like getting married, owning a home, etc. because I've been too damn sick. I struggled to find a career I enjoyed and it was torpedoed because of it.
A family that gives a shit. I'm completely alone. My family of origin is completely dissolved. My parents hate their kids and have sown nothing but discord and division between me and my siblings. I have no contact with any blood relatives. My parents want nothing to do with me. I learned a long time ago that you can't make someone love or care about you. It's painful to be surrounded by families. I spent my 50th birthday alone. No family ever bothered to show up at my college graduations. People say you can create family with friends but I think that's crap. It's just not the same. This issue really hurts.
Good mental health. I've been hammered by extreme treatment resistant depression since I was a teen. This heaviness and sense of dread that never relents. No joy, ever. I can't even enjoy something simple like a sunset. Of course this is exacerbated by feeling like shit physically because of health problems.
Money. If I could ever get healthy enough to work again, I'd like to work and make enough to just have the basics like a simple place to live, food, etc. It's very sad that in today's world a lot of people working full time can't even afford the basic essentials. This along with the rest of the aforementioned all contribute to my desire to end my existence.
A final note. If you are healthy and have family that loves and cares about you, give thanks daily. Health and family are so damn important. Unfortunately I have neither
