I can relate being low due to being disfellowshipped. It is worse than divorce or any heartbreak…and there is never any respite. Family can become callous, hardhearted, and belligerent.
I have found the body is hardwired for self preservation, especially in regard to heights, and it's very hard to circumvent. Hanging and other methods seem quite painful. And the worst case scenario is surviving an attempt, and having a lifelong disability. Fear of pain, heights, suffocation, failing has so far kept me alive.
Sometimes I feel I have a purpose. If I die, then I might fail to complete what I am here to do. Some days the only thing I can do is read and study more intensely. After feeling dangerously low last Thursday evening, Friday I poured myself into printing off and organizing my notes and research materials on 607. Saturday, I bought a new translation of the Bible from Books-A-Million and for a time that lifted my spirits.
