OP, I can feel that you are going through an insane amount of sufferings, especially mentally. Please do know, even in your last moment that you are in no way a coward. CTB is a way out, yes, but no one can say it is the easiest way out. The fact that you contemplated it and are now determined to do it, it doesn't mean you are weak, it just means that life has been difficult for you.
We are here to respect and support each other regardless of whether or not you decide to ctb tonight/today. So if a small part of you is telling you that it might not be the right time, that part might be right. We can't speak for you because we don't know you personally or your struggles. But if something were to come up and make you change your mind, we would love (or at least I would love) to have a chance to hear what you have to say.
All being said, we respect your decision, and we wish you peace because you deserve it.
