How are you doing, @Theendxx? I'm sorry we haven't been able to give you the quick, certain method you long for. As someone said above, if we had that information, this messageboard would be a ghost town.
When you posted this thread in the wee hours last night, it sounded like you might be in the middle of a panic attack. When I say that, I'm not dismissing any reasons you might have for panicking. I don't even know what your reasons are, but I'm not sheltered enough to imagine that people panic "over nothing." You must be in the grip of severe terror and pain to seek out a site where people openly talk about their suicide plans.
I think users here are advising caution for you, since the crisis that drove you here seems to be still-unfolding. You may still be in that first, reactive stage of loss, when people frequently make life-changing choices based on pure pain, anger, or fear, unguided by reason. Such choices turn out to be poor more often than not.
If you're still checking this thread, perhaps it would be helpful to post about what's troubling you. Not because we're hiding the perfect suicide method and will only reveal it if you spill the beans. It would be more a chance for you to examine what has happened to you from a standpoint other than in a bottomless well of anguish. (Although if anguish shows up, it's not like you get an "F" on your project or anything.)
Maybe someone here has faced a similar situation, and can offer useful advice. Probably not advice on having your crisis un-happen, or making its fallout suddenly disappear. Although stranger things have happened. Who knows unless you try? Still, it's more likely that users here can offer advice on how to face disaster with a certain amount of inner peace. And if we can't do that, at least we can validate your misery. No one here is likely to insult you by telling you that you want to end your life for a foolish reason. There are no trivial or foolish suicides. It's about as grave an issue as they come.
