Suicidal Penpal

I met a penpal about last November and I feel really sad about my experience because he was a good penpal but he was depressed. He keeps on wanting to kill himself and always talk about suicide.

He told me I should leave him and focus on myself. I don't know if he means he don't want to exchange letters anymore or he wants to die and doesn't want anyone bothering him with his plan.

Recently this January he told me about wanting to cut himself with a knife and I'm really genuinely concerned. I know there is nothing I can do to help but I hope that suicide thinking will be less in this world. I hope this world will be more fair to everybody. And I hope more people can overcome there problems and overcome depression.

Ps. I sent him the suicidal hotline to call for help . I hope it helps.
