I am so, so sorry. The day I found SaSu (though I didn't make an account immediately; for a while I was just lurking) was shortly after my nineteen-year-old cat, who'd been with me literally since she was born, passed while I was away for the weekend, and due to family bullshit I didn't, still don't, and may never have her remains. Losing her at all was bad enough, but I'd always taken at least a little comfort in having been promised that no matter how much it cost, she'd be cremated so that I could have her with me no matter where I go (as it's unlikely I'll stay I am now for good or ever come back once I'm gone, and I can't bear the thought of leaving her), and even though I've had suicidal ideations my entire life, it's having potentially lost that, too, that finally pushed me far enough over the edge to start seriously looking at methods. Desperate, stupid methods that wouldn't have gotten me on the bus but would have made my life in general even worse, so I have SaSu to thank both for saving me from that and for giving me better alternatives if/when I'm ready to use them, because I still don't know if I can go on. My entire life's been a landfill fire, but the past few years have been like someone's pouring gasoline on it and throwing in tires. I still have my other cat and my guinea pig and I don't want to abandon them, particularly not to the situation I'm in right now, but piggie's a very, very old piggie and I'm not sure how much longer she'll be around herself, and I know my ex would take boy cat if I absolutely couldn't hold on anymore (he was "ours", whereas girl cat was just mine, and we've discussed it before, so that's the one thing I feel secure in). My dog went right about a year ago and her decline was horrible to watch (she crossed over at home a couple of days before what would have been her final visit to the vet, but I wasn't there for her, either; my mom was, but she was MY dog, and I should have been there), but girl cat hadn't shown any signs that her time was up even as old as she was, and she was my soul, and I just don't know if I can. I know she wouldn't actually be in the box, I know her spirit is free and waiting for me, but I'm a person who needs tangible connections because of how messed up my mind is after the years of wrong meds and wrong treatments and all the trauma from that and everything else, I can't always hold on to things mentally.
Anyway I'm sorry for rambling on in your thread; I just wanted to let you know that you very much aren't alone in "this" being the end of the rope (metaphorical or actual, heh), even if there are people in the world who wouldn't understand having this level of devastation over "just an animal" (I am honestly crying my eyes out for you and her while I'm writing this). I don't know how you feel about religion, but I hope you won't be offended if I pray for her soul to be met with one of the gentle guides to help her find her way on the other side.
