Clinical depression, anxiety disorders, chemical dependency, and other disorders produce profound emotional distress. They also interfere with effective problem-solving. Even if you have received treatment before, you should know that different treatments work better for different people in different situations. Several tries are sometimes necessary before the right combination is found. If you are unable to think of solutions other than suicide, it is not that solutions don't exist, only that you are currently unable to see them.
Suicidal crises are almost always temporary.
Although it might seem as if your unhappiness will never end, it is important to realize that crises are usually time-limited. Solutions are found, feelings change, unexpected positive events occur. Don't let suicide rob you of better times that would have come you way, if only more time had been allowed to pass. Problems are seldom as great as they appear at first glance. Then, month or years later, they usually look smaller and more manageable.
