Hamilton appeared on "Glenn Beck" on GBTV.com with guest host Dr. James Robison, Hamilton's pastor with LIFE Outreach, a Christian ministry based in Euless, Texas.
The slugger, who told Robison he's going to "one-on-one" counseling sessions, said when he had his last relapse, in January 2009 in Tempe, Ariz., that he thought things would be fine and that he'd get on with his life.
"This time it's not just, 'OK, it happened, we'll move past it and maybe it won't happen again,' " said Hamilton, who said he's also attending counseling sessions with his wife, Katie. "We want to find out why it continues to happen. Whether it's things in my life -- stress, home things, whatever the case -- those things might be a trigger."
