Husband suffering with depression

My husband suffers with depression and thoughts of suicide. This has been going on for a year now. He has a high stress job along with a lot of family issues going on.

He puts on a good face in a social setting but alone he has his moments. He is trying so hard to flight this for me and our family. He has been on anti depressants for a year now and they seem to help I guess.

We were seeing a therapist for this bit he clams she was no help. I do my best to be positive everyday for him and tell him only the positive.

As a wife/spouse how can I help him? I love him and just want him to be better.
