Stressed to the Max

This is mine and my husbands first baby.

He has been suffering from panic attacks and extreme anxiety. I’ve been trying to help him through but it is really taking a huge toll on me. I don’t know what to do.... I feel like I’m almost to my breaking point. He has always been the strong one and now it’s on me. He says it’s not the baby stressing him out but I don’t know what else it would be.... advice...?
