Partner is depressed angry and thinking of ending his life don't know what to do

Please help give me advise I partner is going through a bad patch a so called friend registered him as working for him when he's not and has been caught claiming welfare while apparently working when he wasn't so now he is getting nothing to help support himself and the kids as well , I at the moment am looking for full time work and what I am getting at the moment is only 160 euros a week that doesn't cover the rent , we have nothing , I'm being kicked to the side and am hurting so bad , he has been saying that hope he goes to sleep and never wakes up and talks about getting a rope and ending it all , that everyone is better off with out him I can't sleep eat etc I'm a nervous wreck, he won't go to the Dr either and it turns into a heated argument .

Is there anything I can do to help him...

Please if any one can advise me and thank you so much for ur help
