Long story in advance, sorry.

My ex and I were together for 6 years. Since October, when we broke up, he’s been in and out of the psychiatric hospital and he started using weed to relieve his anxiety and depression. He got so addicted to it that he literally could not live without it. He went to rehab last month and he left last night, got to a hotel, got drunk, left to the airport, and woke up in the airport (he dissociates) with a huge gash on his arm and throw up everywhere. He’s in the hospital right now and he repeatedly called me crying and telling me he wanted to kill himself. He’s supposed to be on his way to a sober living home. The nurses heard him say that he wanted to kill himself and now they have him in restraints and honestly I have no idea what to do or how to support. I still love and care about him, but I wouldn’t say I love him in the way I used to. Is there anything I can do or any advice ??? Thank you ❤️
