Listen, let's be real for a second, if you were completely 100% certain that you wanted it over and there was absolutely no point fighting any longer, you wouldn't be looking to ask around about ways to do it, because there are ways that are blatantly obvious, they're just extremely scary and painful, and it takes completely genuine determination to end it to go through with them. And i can tell you, as someone who has seen the resources available, there is no easy answer, there is no easy way to die, and all of the methods are either horrendously unpleasant or are more likely to just ruin your body and trap you in a living hell you can never escape from than kill you, or both. Usually both actually. Even if we were to tell you the methods available, along with the risks involved in each of them, you would just feel more trapped than before because it's harrowingly difficult to successfully do in truth. And i say that as someone who has been through that very experience.
The fact that you are talking to people about it, looking for an easier way to end it means that there is something stopping you, be it fear, or knowing the damage it would cause, or hell, maybe some tiny part of you that doesn't believe it when you say that it's all pointless and you can never have a life. And as much as you may refuse to believe it, that thing stopping you is not bad, it's actually great. Hold onto that thing that's stopping you. Stop looking for ways to end it easier and try giving that part of you that believes a chance, because there's every possibility that despite how hopeless it all feels, that tiny optimistic part of you could be totally right, and ending it now would just be throwing away your chance at ever achieving the life that makes you happy.
You can dismiss me as well if you want, as another "unhelpful person that doesn't care", but i'm not feeding you some chirpy optimism BS here, i'm giving you the honest truth that's incredibly hard to see from the bottom of that pit. I totally get that sense of hopelessness, most of the people here do. But giving you methods isn't helping you, as so many here can attest to from being or having been in the exact same place as you.
Please, give this place a chance to help you. Give yourself a chance to be happy again. Talk, to, us. Tell us how you got here. Get it off your chest.
