Whether you choose to live or die is your decision. Nobody can force you to live or die. However, there are few things which you must understand before you take any step.
1. Atma/Soul does not die with Body
2. There are millions of SOULS/Ghosts Roaming earth and waiting for their birth so that their soul can fulfill his/her unfulfilled wish
3. Your ATMA/Soul also feels same PAIN which can be even higher after death
4. Suicide is just KILLING your BODY. Your ATMA/SOUL stays in the universe and roams here and there especially for those who commit suicide.
Even after killing yourself your SOUL will never DIE.
