My wife (f30) is in menopause

She got diagnosed with breasts cancer around a year ago. It's been a long journey with a lot of treatments. To minimising the risk of if occurring again she is now in a medical menopause for at least the next ten years.

I'm so glad that everything has gone so good so far, but everything connected to our sex life has died. She has even stated it that she can't even imagine it right now. I'm so sad and feel like the worst husband ever because I'm sad over such a trivial thing and after something like this.
