Ah, well, remind them of the good things in life. Tell them how it will all get better soon. With those faults that are in their life, try to help them, if you can. If they're religious, remind them about how much God loves them. Don't make them feel selfish about wanting to commit suicide or anything, that really does madami harm than help. Remind them that you're there for them, and that life is worth it. Giving up will get you nowhere. The road is a rough one indeed sometimes, I find myself wanting to die frequently, but it's something that they or anyone must look to God for help with. There are many great Bible verses that go to prove God's pag-ibig for us all, in fact, I'll add an image of one. Prayer will help them a lot. Remind them that God has a plan for us all, don't cut it short, because who knows where he'll take us?
