Can I cut someone out of my life even if they're mentally ill?
I have a friend who is mentally ill. We both bonded over our anxiety and over the years it became that I would advice her on what to do and how to help herself. I ended up taking medication and going to therapy, which I then started advising her on based on my experience. I would even analyse her thoughts and try my best to make her see reality for what it is. Without realising, I had basically become her therapist. This unfortunately has carried on for about 6 years now and she has not improved. She doesn't want to help herself at all. She stops her medication and doesn't apply for therapy (it's free in our country) even though I have told her it's for her benefit. She just sees me now as her therapist and just messages me about her anxieties all the time. I've tried advicing her. I've told her to get in contact with her gp and to get therapy. This year, I've cut down on acting like a therapist and just told her that I can't help as much as those things. She still doesn't want to, still messages me about it all in detail expecting advice and refers to me as her therapist as a joke. It isn't a friendship anymore. I barely talk about myself to her. It's all her her her.
My anxiety has improved a lot throughout the years but talking to her makes it worse. I've gone days ghosting her messages and I've felt so much better. Interacting with her actually ruins my day and at this point I just want to cut her off but a part of me feels bad because she's struggling mentally.
I'm reaching my breaking point. What do I do? Is there any stoic advice regarding this?
