This fall has been a complete shitshow. Everybody in my friend group has been miserable at one point or another, and of course we are there for each other, but one friend, we'll call er "Marcy" is getting to be too much to handle. First off, insecurity in itself is not a big deal, my friend group is basically the bunch of insecure weirdos nobody else wanted, but Marcy shows her insecurity at any time she can. She writes about how things are terrible, she calls all of us constantly, sends us upwards of 10 messages an hour even if we don't respond, and is generally exhausting.

Marcy has been like this for about two months, mostly she has been insecure about her relationship, and her smoking, which is understandable. However, she always brings it up to the detriment of others. For example, I'm dealing with pretty severe physical/mental health issues, but every time I've tried to get advice she starts talking about her problems. She had a complete meltdown at my birthday party because she was angry at her BF, which I took in stride, but I'm getting seriously annoyed.

It would be one thing if me and basically everybody else weren't knee-deep in our own shit and drama, and if she didn't bug us constantly. I've replied and tried to console her every day from october up til last week when I just put her on mute, and started responding when I felt like it. It's really stressing me out, and everybody else is sick of it to. Her boyfriend, a close friend of mine basically broke down because she is getting to be impossible to be around. 

AITA for being really sick of her? I love her as a friend, but I don't want to help anymore. I've tried, but I'm sick of it, and my health is already going to hell without this drama.

TL;DR: Friend is severely anxious and makes it my problem. She made my birthday party a scene for her to have a meltdown, she spams me and the other friends constantly and even her BF is getting nowhere with her. AITA for not wanting to care anymore?
