I hope you don't actually end up following through on this, or that if you do, somebody will be able to get you to the ER before you pass away. I'm not saying I think you should "change your mind" considering you're going to do what you want to do, but I hope you don't still want to do this in 2 weeks. I'd recommend waiting for a while and living your life as if each day is your last, considering your intent. At least see your family and try to reconcile any past disagreements or other problems that put tension on your relationship and affected you life negatively. Call your friends and ask if they want to get lunch or coffee at the very least. There are always aspects of life that are positive and pleasing, while there are also always parts of life that are negative and difficult to wake up to every day. You can always wait...but you can't reverse what happens if you decide to go through with it.
