Friends

So I have this one friend. Let's call her B. So B and I have been friends since we were in grade 9. Recently she's been very clingy and annoying. She's the type that gets mad when I hang out with my other friends without her. I know, its not a healthy friendship if she reacts like that. I find that she takes out her issues on me. She's very rude to other people and when I call her out on it, she gets mad at me. We had a talk about our issues and it ended with her calling me a shitty friend since I've been getting mad at her lately for the littlest thing. She keeps trying to touch my hand and hold my hand, which makes me uncomfortable so I tell her to stop. I hate being touched so I snapped and said "can you not". She then goes and tells my other friends I'm being a bitch.

I don't know what to do anymore. I distance myself from her and she keeps texting me saying she misses me. I think she gets a little too attached. She goes to my other friends and brags about how she's my bestfriend, when really she isn't anymore. She tells me about her issues such as her harming herself because she's depressed and idk what to say or do. She told me I was bad at giving advice. I get that she has issues and wants to talk about it. I try to help but it ends up just us in a fight. Im trying to distance myself and kind of like, not be friends anymore since our friendship isn't a healthy one and its taking a toll on me but she just keeps coming back to me.

Any advice?
