One difficult issue about CTB is that sometimes you may think you do not want to die or feel a little bit better than usual. And when it is getting better, you can think that may be CTB is not necessary for you, maybe there is a way out. Or when you already have everything planned you realize that certainty about the future makes you feel more calm. Although you may know you will die anyway, sometimes it feels like you have just thrown away that burden from your shoulders. Or out of the blue it starts getting worse.
I think if you have any doubts about whether to stay or to go, it would be better not to hurry. You can always stay there, talk to other users, maybe do your own research. It is normal to hesitate, especially in decisions like that. Just know you are always welcome here!
