If you act insecure and play silly games in relationships, get your act together so you won't repeat the games in your next relationship. People die often from causes related to loneliness and broken hearts. Don't just blame him or her for your unhappiness. Get it together and much of your distress will go away. To ask for help in a difficult situation is not a disgrace but a sign of inner clarity.
People die from one intense experience or one sudden disappointment.
Don't allow any one big problem to determine your fate. Of all the dangers in the world, the greatest are the dangers we create for ourselves. What you are feeling is not the love of death, but perhaps the death of love. The first death is permanent, the second death heals. Your pain right now can create a small critical time when change can occur.
