I understand. But having been there myself and now being out of that state, I can safely say that whatever you're feeling right now is likely going to pale in comparison to attempting suicide in your current state and then failing. Failure is not something you want to add to your plate, as it can vary between additional psychological stress/damage to actual physical damage from being maimed. It'll only make your hell even worse. And being in the state you're in is precisely why you shouldn't act on it right now, in my opinion.
I cannot tell you what to do, as it is your choice and your CTB. All I can do is look from the outside in, and give you information and an opinion. As Aprilfarewell said, you have the right to act as you wish and you may take your exit whenever you feel like it. But this is just my opinion I'm offering, so at the very least you should take into consideration the opinions of people here, it can only help.
I truly wish you well whatever you end up deciding to do.
