Pangs of loneliness...Question for one and all.....

Have you ever underwent through the deep abyss of loneliness?I think all people has to go through it in their life...But how do we confront it..I am still trying to find exact answers. Right now I am experimenting with all kinds of possiblities(But mind you its an experiment). Just to make matter more precise take an example of the one whom you loved and lost or it has come to an abrupt end. you after lots of efforts are unable to keep control on your emotions as it keeps on coming in your thought.Also you have to face him/her some times and all those past memories starts unfolding before you again and you feel as if nothing has happend just for a fraction of seconds. But that fraction of second gives you 100% satisfaction and from there you start saying/blaming yourseleves or later that "Had it not been and so on".For the past so many years I too have underwent through so many pains but it was more like sham pain as I could forget it easily within a span of short time.Off late I doubt that the level of pain increases with one's age. In other words as we mature so do our pains. This is what I feel right now.Especially when you are alone or not doing something then at that instant of time life becomes miserable.You tend to think all those which have had happend with you and this is how we make our life more miserable.But how to come out of that misery. This is my question from all of you.How to face life if something similar have happend with you. What could be the best remedy in order to quash all those old memories if not able to forget all.Since this problem has to be sorted out quickly otherwise it will take a toll on other part of your life. Is there any way out for this problem. Though prople will tell/advise to come out of it but really dont know why I am trying to get in. I guess this could be the reason for my misery. But something has to be done quickly otherwise I will losse all those small remainings which I have earned in 26 years of my life span.
