Everything’s gone wrong, no one else listens or cares. Final attempt at calling for help

Literally everything that could go wrong in my life has been. Sure my life was never great but now I’m 18 almost 19 and everything’s a wreck. I finally get a kitten after years of begging? My senior cat almost fucking dies and his vet bill is 1K. And now my poor kitten has an eye infection, I get a 100+ dollar costume to go out with my nephew for Halloween, literally everything goes wrong and I just sit inside watching YouTube because no horror movies are good. I want to watch a fucking movie, my 300+ streaming services permanently ends it services. Now I need to try and remember all the movies I had saved and find streaming services that even have them! It’s just been one thing after another my entire life and everyone acts like I’m freaking out over minor things when it’s been my entire life going wrong, those are just the major 3 things from the past TWO DAYS! ok well my cat got sick a few months ago but he’s still healing and that left me fucking traumatized, I kept thinking it was all my fault. Every time I try to reach out for help to anyone no one listens or cares or even responds.. I think this is my last attempt at reaching out for help, I’m truly done. This world isn’t even made for people like me, I’m too autistic to function but not autistic enough to get help or be taken seriously.. I’ve been hanging on for my nephew and pets but- I think they’ll be ok with out me. This is my last attempt at getting help, after this I’m just- see what happens I guess. The sad part is i dont know if i want help or to just let it be over with finally..
