If you don't mind me asking, why do you want to ctb ?
thank you for asking, the main reasons are:
1) my laziness and related issues such as easily being overwhelmed when trying to "learn" a new thing, or not being able to focus when reading
2) loneliness(which might have a little chance of being solved after the first problem is gone)
3) the state of the world (its unfairness and the existence of evil) and my emotional sensitivity about it
4) life not being interesting. nothing fantastic exists and i don't like that
i learnt that being in love quite literally solved all of these issues but i'm not willing to try furthermore. life is too hard for me, and thats okay. not everyone has to live. every problem has a solution and the best solution to my problems is death. i am glad it is. because its easy to die :-)
