Need help Please dont be rude?

I aint trying to be funny, no trolling nothing like that. I'm in serious need of help. My boyfriend has gone a little or actually beyond crazy if i may say that.I need help and I am not sure if anyone can help me or not. I'm doing this in secret to be honest I am terrified that if my boyfriend found out I was doing this, God knows what he would do. My boyfriend has some issues, serious issues and I am scared to death he will commint on them. He is always threatening to kill himself or us. He is having sucidial thoughts and has once attempted in front of me and my kids. He has anger issues too and has punched holes in my walls at our old home a couple in our new home. He has even broken the door knob on our bathroom door. I fear for my life every day and I shouldnt have to. I am not looking to have my children taken away. If I must leave I do have a place to go but I refuse to go to a woman's shelter or refuge house.. I have pets also that I fear he will kill if I leave them here and I can't bare with the idea of putting them up for adoption or putting them in a high kill shelter. I have a home here that is stable it's just him that isn't stable. I need to know how I can have him put away for his own safety and for his health. He needs help and I am scared I will come home and he has killed himself or worse. I don't wanna live in fear every day but he needs help. And I really truly don't want to leave here and have him looking for another woman with or with out kids to do this cycle again. I feel like he needs the help. He isnt working and neither of us have income. I know that already plays a role in his issues and the whole fact of knowing if I leave with my kids that he will be loose to do this again scares me. He needs mental help and I know there is someone out there who can help him. Please tell me there is some way I can get him the help?! I don't want it to be known that I am the one looking to get him the help. I fear it may send him over the edge again. Please help us. He needs some kind of medication and consouling. I would do it myself but I do not have my degree in it yet.
