@greygoose first off, I'm sorry to hear about what you're going thru. Truly. As easy as it is to say, and as truly difficult as it is to
actually do, try and enjoy every single moment. Life feels too long, and then it's far too short. And this is coming from someone who has been on a steadily downward spiral for some time. Spend your time with those who you care about and those who care about you.
Although I don't have a "family" of my own, my dogs are my brothers, my companions, my kids and my only friends. One of them, Mack, was diagnosed with incurable cancer earlier this year and he's been on chemo ever since. Knowing full-well there's no cure and the chemo treatments are only a temporary ease of symptoms (and are no longer effective; his cancer is no longer in remission), I still give him a pat and tell him I love him every time I leave home. I can't help myself.
The thing is, I would take that terminal cancer from him, from anyone, in a heartbeat. I know what it feels like to live for nothing. This hobby has provided a distraction for me, at the very least during some personally very dark times. I hope it provides some relief to you as well.
Take care, man. Tell those who you care about, who matter to you, how you feel. You never know what tomorrow will bring. None of us do.
