Help with hubby

I wasnt sure where to post this so I though maybe other hubby's may be feeling the same. My man lately I feel has been suffering from some anxiety. Maybe a lot of the changes are catching up to him and worrying him. He will be a first time father, I have a child already and he is feeling a lot of stress thinking about being a good dad to the babies. I dont what to do or how to calm him. Hes been feeling very and weak, restless, and fatigued. So I'm thinking he's super stressed and anxiety ridden. Does anyone elses man feel like this or have ever felt this way? What have you guys found that works for your stress and anxiety?
