I daydream about it constantly. It's the single most intrusive thought I have ever had. It's much more potent at night, so that's when the bulk of my planning happens. I have no real guilt or issue with how this will impact others. It's a decision that simply isn't about them. It's also relatively easy for me to see that there are some core people who could have made different choices if they were concerned about my happiness, health, and safety. Some things just are what they are.
I used to imagine this act as more theatrical than what my current plans are. Like some others have mentioned, I had plans around I would present myself. I used to think I would do it on some landmark day. Now, I just want the least fuss as possible. I intend to dress comfortably, create a calm surrounding, and have all of my resources in place. I'm prepared to be uncomfortable for a little while. I'm working towards being prepared to survive. I have three day weekends and a relatively private living situation, so I'm confident that I can have the time and space required not just to follow through, but also to recover should I not succeed. The ordinariness of my current plan provides me with a good degree of comfort. Having a plan makes the persistent anxiety and physical pain a little less sharp.
