My boyfriend and i had a very emotional phone call last night,both of us crying most of the time ,we started talking about life he said he was scared of the future and he didn't want to be a failure then about 20 minutes later told me he doesn't want to live anymore but he doesn't want to hurt me or leave me and that I'm the only thing holding him together

I've known since before we started dating that he felt this way about living and I've helped him and talked to him about it times before it hurts me everytime he gets like that because im the only person that's actually ever cared for him (in a relationship way) and it feels like I'm failing him . ..I'm not asking for help or how to make it stop I know him feeling that way won't go away just because we are together ...I just needed to get it out my head 😔😔😔😔😔
