Ken Seeley, author of "Face It and Fix It": If you've got underlying issues, why not deal with them and have more years of happiness? Sonia and Julia were extreme examples, but you don't have to wait until things go that far.

You wouldn't tell a cancer patient to wait until the tumor is the size of a football to treat it, but that's what people do when they don't deal with LIBs.

What types of LIBs do women in their 20s tend to have?
KS: Usually it's weight. You gain a few pounds, so you go on a diet and exercise. You can go back and forth through your whole 20s and 30s until you realize that the roller coaster isn't stopping. It often takes years to realize that there's a deeper issue there.

Bad relationships and tolerating emotional abuse are common, too. Of course some are learning experiences but you don't have to continue down that road and undergo years of unnecessary pain.

Texting and e-mailing are good examples of behaviors that are considered acceptable but can become too much. You're not really dealing with life, you're hiding behind the computer.

What's the solution to handling an LIB?
KS: You have to break through the denial. If you can break down that wall, and find five people who'll work with you and tell you the flat-out truth, you can tackle LIBs head on and find what makes you happy.

How are Sonia and Julia doing now?
KS: They're both doing well and responding. I loved when one sister said, "If my sister doesn't change, I can't go back there." They were concerned for each other and desperately wanted to change, but didn't know how. That's where I come in. I help people find the blueprint and tools to make the changes they need.
