I am sorry that you are feeling this way at the moment, it must be hard to put into words the full extent of how you are feeling. There was a time not too long ago I was in the same place. Had everything I needed and was ready to check out because a bunch of triggers happened that day and it was well before the optimum time I had set myself to minimise any trauma by those who survive me. I have had the honour that people have spoken to me in private, these people do not really post much on the forum. A few hit a moment and decided to go on impulse. Some succeeded and some failed. The reason they failed is that once they drunk it, a sudden realisation came to them that this was not their time and they had so many things to do. I would urge you to look at that fact. Preparing is not just getting your regimen together. There are things like letters and other things not relating to the act itself that needs to be done. Hoping that you can make your way through today. i coped by getting out of the home and going for an extremely long walk, finding a coffee shop, sat down, read some non suicide related things on my phone and people watched for a while. It helped me to get off the ledge so to speak.
