Is it wrong to want to die

Is it wrong to want to die? Because I want to die; not now; but eventually; and it is not fair to the dieing and the dead that i should want to die. I take up there space there life's there continuation. I don't understand this; I want to die; the darkness that I crave to envelope me in oblivion. I want to become one with the night for life to end and see what is beyond; but is there really a beyond a heaven; i think life will start anew. Its not fair that i as one that had a good life would wish to die; and yet there are those who are dieing; so young; too young; too soon. Do i not just take up there space in this world. I want to die; eventually but not now; eventually; I want to die; because the space I take up is some how unbearable; then why am i still hear to feel so much; too much wishing I would not feel so much.
