If she has a medical team responsible for helping her with regards to how to treat her. They should be able to advise on counselling in your local area.
There are other counselling organisations, I was happy to get my GP to arrange through first age uk, then mind.co.uk! With their help, I feel so much more confident, my depression has gone, but still have some anxiety.
I have a rare condition that took time to get my head around it all but we can be so resilient. And if it explained to her and understand what is happening, I am sure with the right support, she will be able to overcome this.
