You don't have to have a physical relationship with someone other than your spouse or significant other to betray him or her.

I do not know Rep. Weiner. But I do know he seems to have the features of a narcissist. Narcissists feel empty. Narcissists feel invincible. But their emotional landscape is barren.

If you don't want the world to see something you're sending, stop and think before you put it out there.

I tell young people all the time, and now I'm telling anyone, no matter what your age: You can't take back the stuff you put out there on Twitter and Facebook, even e-mails.

The term 'doctor' has been so abused lately! I didn't live in a hospital for 10 years so that term could be bastardized.

Many aspects of the George Zimmerman trial have deeply affected me.

From a health standpoint, I have metabolic syndrome, I have high triglycerides, low HDL, body fat centrally located, high blood pressure. Running really helps control my weight and that problem a lot. So if I am not running three days a week, I really miss it.

In terms of establishing a connection between a therapist and a patient, that work needs to be done in person.

Treatment of alcohol addiction can take many forms.

I have a pretty keen ethical compass.

Secrets keep addicts ill and cost lives.

I'm too busy to block everyone on Twitter.
