I'm an aspiring writer, and I'm planning on ending my life after I end my book. I've been holding on a single branch for too long, I think leaving this world with a remembrance is a great way to say goodbye. My story is about a girl who got lost into another world, she had adventure there with here imaginary friends and her dream family(not a dysfunctional one). When she finished her mission and found her purpose, the story ends with her saying goodbye to that world.

Hey, I may not know anything about you but please don't kill yourself, what about your family or friends? There is always someone that cares for you, wouldn't he or she be sad? I'm not going to say to live just to suffer but I don't know, isn't there anybody for who you would stay here, even though all your problems? You're a writer, then write down your difficulties, I don't know, but express your suffering in another way...
I hope this reaches you and, if yes, you'll consider what I'm saying

That is a very selfish thing to do, you know. Taking the life someone gave so much effort into giving you is just a waste. On top of that, if you truly want to be remembered in this world, be remembered for your life as a person who was strong enough to turn away from the temptation of death. Do not be remembered for your death as a coward who tried to escape the painful parts of life. If you still wish to commit suicide after hearing this, then by all means, do so, you coward. :)

The world is messed up but dont give up, there sre lot of intresting things,, if you die you are gonna make many sad , your parents ,siblings , friends ,and even your fans.

but what if the story is so good that people want a part 2?

what's all this negativity here? telling someone they're a coward in this situation is really not the best thing to do
