No, suicide merely delays the inevitable. The same problem you sought to escape will be patiently waiting to manifest in the next life; only the stage and actors thereon will change...the play will remain about the same.
There are valid uses for suicide. For example, if you have a painful and wasting disease that will kill you, but make you suffer for years first, or one like Alzheimers that will turn you into a mental vegetable. Them that say suicide is for cowards are them that will most likely die crying and begging their noxious Lard for one more minute of life, being so very terrified of death! To welcome the end with open eyes requires a courage such cravens will never grasp.
There is not much in this realm we have true control over...but the time, place and manner of death is ours to decide. We do not belong to some deistic god, The State, some Confucian concept of society, our parents and family, friends nor any other outside entity. Each being belongs solely to himself, has dominion over his body and life, owing neither allegiance nor obedience to any other.
