For year I have had a friend that the friendship has always been very one sided. She has severe self-esteem issues, mental health issues, and in general a hard time keeping friendships. From the start of the friendship it felt like it was something that would be one sided and I would give more than I would take, which I accepted. Recently I have realized that the relationship is incredibly unhealthy. For example: all of her sadness and her emotional needs to lays them on me, which even when I have told her I have my own life stresses and its unfair for her to burden me, she is usually good for about 48 hours before she once again weighs them on me. Another thing of the last few months is that she seems to be copying everything I do. Examples: I have gotten a few different tattoos, which she then immediately gets similar ones. I dyed my hair and then two days later she dyed hers. She has told me that my body type and size is exactly her goal. I am planning on moving to a different state, which she has now expressed she wants to do as well. Most recently, I received an awesome pair of leggings as a Christmas gift from my fiancé, which she immediately went out to buy herself.

I just don't know what to do. I'm not sure if I'm over reacting, but I recently feels as though she sees that I am happy and content with my life and she is copying everything I do to try and achieve the same happiness.

I do not like to hurt people, as it is not in my nature, but I am starting to feel the toll that she is taking on me.

Any advice on how I can proceed with the least damage doing?
