Nervous breakdown help?

I am pretty sure DH is going through one.. all the symptoms, multiple trips to the ER because of panic attacks, depression, heart pain ect.. and no one has diagnosed it. We are going through a bankruptcy, losing everything ect.. HE lost his job/income last year and it has been downhill ever since. I don't know what to do for him but I was hoping maybe some natural remedies can work (he refuses to go on something like xanax or ativan for other health issues). He also has family issues going on with his dad ect..
