Hi and welcome to DWD. It's lovely that you've joined to try to help her - In our relationship it's my husband who has depression/anxiety and so I'm in your shoes so to speak, so I do understand.
Where have you moved from? Have you/has she looked on things like facebook etc for local groups which might help? What about any hobbies she has to get to know others? What's her genetic disease if you don't mind me asking? Maybe a support group? Living with progressive illness is pretty sh(t tbh - I know I am and I know others here who are too and it can take every ounce to hold together the "I'm fine" to others.
Has she seen a GP? If she wanted to, then she could join here too and we have enough private sections that I could allocate you each an area so you could talk privately if wanted/needed..
