When you and your partner are suicidal and depressed

i can barely over come my depression (I've been in therapy and medicated for the past 12 years) and this week my husbands tried to kill himslef because he was sooo depressed and thought I wouldn't be able to handle his depression as well, so he goes ahead and tries to kill himself, we barely made it to the hospital and then he refuses treatment, he got his cuts cured and we were sent home. I stay up all night since then because I'm so afraid he goes and tries again and this time I won't be able to make it on time.
