Two summers ago, my son ended up hospitalized three times for suicidal ideation. I understand your fears. The uncertainty is excruciating, isn't it? Your role in this is to facilitate finding him the right help. You can't fix this for him but you can be his support while he goes through this process.

I think in an odd way, my son and I have a stronger relationship now as he and I have an empathy for each other's struggles. We were fortunate. His depression was apparently situational and temporary. He has since done quite well with no relapses. I hope things will turn out well for your son also.
