What can i do to help?

My wife has been diagnosed with PCOS. She also has depression and a very picky appetite (both due to childhood trauma) we eat a lot of frozen chicken and protein pasta (i've always been a meat an potatoes guy, but i've changed up my diet to meet hers) i've tried getting us on a better diet. I got her into biking with our kids. We have been TTC for a few years, and our current kids (twins) were a surprise to both of us.

What else can I do to help?
