Trying - It sounds like she doesn't know how to handle or react to what you have gone through/are going through. I know, you would think that people close to us that have some mental illness issues would be the most understanding, but sometimes it is just the opposite.

When I had my breakdown, my two best friends - we were always a 3 some whenever we did things together, both bailed on me. One was on meds for depression and anxiety and one had been previously, so you would think they would understand and be able to stand by you, but I think it almost forces them to have to look at issues they dont want to face.

I am sorry you are having a rough time. Just be there, be nice and try not to have high expectations from them. Do your best so that you can continue to look yourself in the mirror and say you did the right thing.
