Should I end my friendship with my friend who has an alcohol dependency?

Anonymous
My friend of 2 years has a serious alcohol dependency. Like she has a hernia/ulcer and still won’t give up the alcohol (she’s 30). I met her while studying a short course. She suffered a lot of loss young (mother and other family members). She’s never had a job or boyfriend or anything. I feel too guilty to end the friendship but we’re just not suited to each other because I don’t drink any alcohol and she keeps trying to persuade me to drink with her. I’m really sick of it. She wants to go out with me for my birthday soon but I don’t want it. Can someone please advise me how to go about this? I know what I want and need to do but I just need to stop feeling so bad for her when she’s not doing anything to help herself. Today I asked her would she ever give up the alcohol and she said no.
