Is it normal i want to get away from my friend?

I have a friend who is 2 years older than me, we are both in our early 20's. She is one of my closest friends but sometimes I just wish I could get away from her. She tells me all her roblems, I know friends are there to hear problems but she doesn't keep any problems to her self and sometimes I feel very overwhelemed by them. I also know she lies to me and our other friends, she has problems with being too thin and told her mom she wasn't eating but I see her eating all the time. I my self am overweight and she makes me feel very fat when she goes on and on about how fat she is; she is a stick figure. Also I cannot say I like anything because she will say she likes it and has no ideas of her own. She also swoops in on all guys I like and usually ends up dating them and breaking up with them and now she thinks all the guys I know are horrible. So my question is it normal I want to get away from her?
