I am going to agree with Kitten645 and Aisel, i may sound harsh but i would leave well alone, and i would not let her in to my life, obviously nothing about her has changed, and a lot of what is happening to her she brings upon herself, if she is such a negative, unkind person, what can you expect in return? and yes you can be addicted to food, but it is still up to you and you alone to try and do something about it, addictions can be overcome like anything else, with a lot of hard work and committment,and they never go away completely ,but you just have to work hard at keeping it at bay.

I would not think bad of you,if you did not renew this friendship, you have to think of your own well being as well here, negative people can make you so unhappy and cause so much stress in your life, and i speak from experience,to a point where you yourself could become ill from the stress of it all.

It may sound selfish,but sometimes you have to be selfish in order to protect yourself,you may well be taking on much more than you can handle, and it is not like you don't know what she is like.

My advice is to NOT get involved with her again. Take care now.
