My 24 year old son told me he's having suicidal thoughts because of a body issue and as a single mother I don't know what to do to help

He came over tonight and we spoke about his depression and his treatment. He's been especially down lately and when I asked him what, if anything, had happened, he told me he is not well endowed and that has been making him want to end his life.I tried to comfort him and calm him down but he left my house in a rush.He sent me a few texts explaining that, while he has been thinking about and is considering suicide, that he is "not there yet" and that he "just needs to sleep so I can stop thinking about it".I'm out of my depth, here. Please help me help my son. via /r/Parenting http://ift.tt/2m6evFA
