I NEED HELP💔😭😭

So lately I've had some issues with I want to say my SO but lately it's been pretty off and on with him. I have gotten depressed and tonight we got into it and I told him that I don't know what I would do without him and that I love him too much and that I am willing to change my ways to better our relationship. But I guess that wasn't enough. I let the words "I'm going to kill myself" slip out of my mouth and it really hurt both of us. I've talked to his closest friends and mine as well and they want us to get back together. I've sent him this but I don't know what more to do. I am a emotional wreck yall😭
