CTB would obviously be freeing, but what's also incredibly freeing is having a plan to CTB, and then having a reason to hold off. Whatever that reason might be for you. A future goal, a loved one, whatever. I'll say from personal experience, life is a lot more fun when you have that killswitch with you, because the pressure's off. You're not here by force, you're here by choice.
If you're still on the edge and not committed yet, that's the best advice I can give. Find your "escape route" if you really need it, but just hold off on actually using it. I turned back from an attempt days before I was supposed to do it, more than once. Call it irrational SI or just seeing life from a new perspective, but when you're really heading into a CTB attempt and mentally preparing for the end, life starts to look a lot more tolerable when you've only got days left of it. You start to appreciate the good parts: the people you care about, the good memories from your past, etc. So I decided "you know what, lemme hold off for a year, cross out some items on my bucket list, and just try to enjoy the extra time."
