A bit of help...?

Have you let go of something in your life? Did someone special move away? Have you commited a sin and afraid that God may not love you anymore? Have you done something horrible to someone else? These things can trigger feelings like this, but if you ask for forgiveness and truely mean it, then it should go away. If someone moved away, then just let time heal that wound. If nothing like this has happened, then I'm not sure what it is. Details appreciated.

sounds to me like you may be suffering from mild depression. This is a physical illness caused by chemical inbalances in the brain, which is often brought on by a stressfull event - but not always. I used to be intolerant of depressed people and would just tell them to "get a grip" until I suffered depression after the birth of my son and realized that it's not that easy. I got over it by meditating and fighting the symptoms everyday and also by taking St-John's Wort herb. There are drugs that can help and my doctor wanted me to take anti-depressants. I don't recommend them but if you find your symptoms getting worse, where you are thinking about dying and the sadness just becomes unbearable, go see your doctor.

I agree with the other answerers but also i think that it might be a sense of longing for something. Maybe there is something thats missing in your life your heart knows that you need it but your mind just hasnt processed it yet.

what ever the case is I hope that you get through it and find happiness again.

Good Luck.
