HELP!!!! Have No Idea What To Do

Today I was in the shock of my life. Even though things have calmed way down. I still don't know what to do or how to handle this situation.

I was visiting my mom today while my husband was at work. I've been a little frustrated with him but i hadn't verbalized it to him. He works 45 plus hours a week plus goes to school on his days off to become a paramedic. I am supper proud and I don't except much from him right now. I take care of our newborn and try and keep up with daily tasks.

Anywho he feels like he has failed some how. He is always tight on money. So am I right now being on Maternity Leave. He feels he has failed already as a father because he doesn't have time. It has all built up inside of him. I came home to him writing a suicide note with his hand gun sitting beside him. He feels we would be better off without him. Which i reassured him that i don't want to do anything without him.

I live in a pretty secure bubble and never have experienced anything remotely like this. We have since talked and he is doing better, but tomorrow he is going to see a doctor of some sort. He said he would, but ill force him to if he trys to change his mind.

Any advice here?????
