Help Any available methods in Mexico?

[E.B.M]

I sincerely don't want to make it to next year, been moving my date over and over again for the last 2 months but yeah I'm pretty much done with stuff, can't stand it to be honest, can't bring myself to do partial, full or self harm
would simply like to fall sleep and don't wake up to another alarm
Been looking a lot for SN but it seems to be quite a problem, bought a batch but for some reason it doesn't seem to react on a SN aquarium test at all, blood test does work but I dont feel safe with only one of the tests working

I'm open for suggestions or if anyone knows about any source I'm more than glad to hear it please
