I appreciate it, the support, but this all feels so much like deja vu. Every time someone says they are going to do something extreme everyone, even absolute strangers, absolutely panic. Every time you get a broken heart, it's "theres plenty of fish," and I feel bad all the way up until the point where it fades away to the dullest shade of gray. I feel so helpless. I want to make a violent change. I want to be mad and have people recognize it.
Yeah, people tend to panic. I was actually afraid that you would no longer post, implying that I knew someone was about to off himself and I couldn't do squat... I care, and so does everyone else around here. So do us a favor and wait a bit, try to get over your relationship issues,
see a doctor if you think you're ill, and only then make a final decision. There's a Nietzsche quote that goes something like "The thought of suicide has helped many a person get through many a dark night." Everybody thinks about that stuff now and then*, but as morning comes, these feelings go away.
As to your preferred method: Poisoning yourself is usually a bad method, as things can go very wrong and leave you alive but crippled, and even the prettiest corpse is not a pretty one if it's covered in vomit and other fluids. To both set a violent example and kill yourself effectively, I'd suggest a long drop hanging - at least that's the method I'd choose.
If you want to talk in private, my PM box is open
*Proof: In a conversation with your friends and/or aquaintances, ask them which method they'd choose to kill themselves. Chances are that two thirds of them will not have to think long before coming up with a method and good arguments in its favor.
