Husband tried to commit suicide

I know things weren't perfect, but never would I expect this. He suffers from bipolar depression and anxiety, recently we were involved in a car accident that resulted injury to his back. Because of this he's out of work. We have a 2 year old and a 2nd baby on the way. All he care about is his girls, and I know not being able to provide is tearing him apart. Just wanna see him and let him know everything will work itself out. We're lost without him. I'm sitting here wondering if I pushed him too far, did I put too many expectations on him, what did I do wrong to make him feel this way? I always recognize the signs of his depression early on,how did it get this far? It's been over 10 years since he first tried. I just wanna hear his voice 😥😥😥😥
