Occassionally on this forum and on the podcasts the topic of suicide, and also chosing to end one's own life when terminally ill, etc. has come up. And I feel the need to bring up and share some "therapeutics".
Given that we believe that we only have this one life to live (no-rebirth, no second chance) this means that ending one's life is rarely ever chosen unless out of great necessity ( Cassius I know there are sources for this in Epicurean writings but can't remember off hand).
Ideally I would recommend someone should seek out the professional help of a therapist, to effectively remedy repeated or on going suicidal thoughts.
For those who may occassionally have milder moments of considering the meaning of life and only briefly encounter suicidal ideation, I would recommend this very good article, which also brings up good points to bring more meaning and fulfillment:
