Help (tw suicide)

Hey, so my friend really needs help. Tgey're the lowest they've ever been and want to donit tonight. Their mother gave away their dog and that was the only good thing in their life. They don't want to get any services or police involved. They make themself at fault and think they need to be punished. I really don't know what to do, i offered them to call me. We live in germany, are both minor and are online friends. We've only known each other for a few weeks and i don't know exactly whee they live (also 5 hours away so i can't go to them). Thank you.
