This VOID!! What is WRONG?!?!

This VOID!! What is WRONG?!?

I cling to just about every b/f I've ever had, regardless of flaws, regardless of anything, I hang on to the guy for dear life and will do anything for them.Looking back(since I have no man in my life at the moment)I don't understand why I act the way I do, why I am so desperate.Many of these relationships end quickly too, for most guys think i'm crazy or something/ have no life etc....And they are right, but I can't change.I only care about "my guy" that's it, and it's been that way for years.If i don't have a b/f in my life...then i'm extremely lonely, not a happy person, and just extremely desperate and nothing is worth doing.How can I stop this mentality/behavior of mine? I have given up on friends,since no one understands me anyway, and i'd rather be alone then put trust in anyone and have them hurt me.The only people i trust and put my heart and soul into are my ex b/f's, they know the real me,and usually except me for the extent of the relationship.Help, what is wrong w/me? Thx

Lisa,
There is an author, Melody Beattie, who wrote a book titled, "CoDependent NO More." In the book, Melody Beattie explains that a codependent is a person who believes their happiness is derived from one person in particular, and eventually the codependent becomes obsessed with controlling the behavior of that one person.
Now, you might say that you never tried to control your boyfriends. but you already admitted that you "hang on to the guy for dear life." If you feel that your life is dependent on another, then in order for you to survive, the other person must meet YOUR NEEDS.. Right??? Think about it.
This become all about YOUR NEEDS. So the truth isn't that you are truely meeting his needs. The truth is that you are meeting your own needs by using him for dear life. The boyfriend can not meet such a demand and decides to cut off the relationship. And this is the right thing for him to do and for you.
The concept of a CoDependent is rooted in the 12-steps of Alcoholics Anonymous. People became aware of CoDependents because they first became aware of Alcoholics. As it turns out, for most AA people, there was always an enabler or someone that cleaned up the mess and "loved" the drunk thinking that one day it will all get better by itself. It never ever ever does.
Just like AA, you must seek help outside yourself. Now, that help will not come from me. It must come from another female who has dealt extensively with their own CoDependency. So read the Book, CoDependent No More. Then decide what to do next.
Good Luck
