Hi Megan, sorry you are not gettimg the support you deserve, maybe some people can't handle it when they are down, but that said a best friend is usually someone you can count on through thick and thin. I have been suffering from depression because of my partners drinking, if anything it has made me more sensitive to my friends and their problems, but we are all different. Best if you are totally honest with her, she will probably realise that she needs to give you more support-hope so.
