Unbalanced life

Do libras live an unbalanced life all the time? Or does it go away? How can a libra cope with stress without making them unhappy?

I find that I'm always off balance if I'm not in a reciprocating relationship.
When I am- I am full on 100% , just conquering the world. When it ends, I become disillusioned and withdraw to go through mourning- and then I get comfortable being single and I'm a total dick to everybody. And I'll just stay that way for looooong periods of time. Like, years. I'm usually a good 3-5 years between serious relationships because I spend my time alone and just having occasional flings. It isn't until I fall in love that I'm able to feel whole again.
It's terrible.. I hate feeling like this all of the time and it happens often because I always choose the wrong type for me.
Closeness and affection usually lift me out of my times of imbalance.
