Please help. I am 46yr old mom from TX. My 22 yr old son just called me from NC where he lives. He has been drinking and seems suicidal. He talked for over an hour about how worthless he is and how he hates himself. He said it would be so easy to just end it and the only reason he hasn't is because of his younger sisters (ages 11 and 13). What should I do? I listened and told him how much we all love him. What else do I do?
