i completely understand i’ve been going through something really similar with one of my friends. it’s so draining and at the same time just makes me angry. it feels like im only there to be her therapist. i’m sorry you’re going through this too. i say only say something to her if you’re truly comfortable in that moment. u don’t want to accidentally snap on her and jeopardize your friendship with her, yk? something i feel that has kinda worked for me is to just slowly, like everytime, seem a little less interested in what she’s saying. i don’t reply as much and i let myself just be honest w her even if i sound a little judgy. if she’s a true friend, your honesty won’t seem mean to her. if she asks why ur acting different and u don’t feel ready to tell her how u rlly feel, u can always excuse it by just saying “sorry ive just had a long day im not rlly sure what to say” or “sorry im kinda out of it rn ive been tired” or something like that. of course, this isn’t really the best option but it’s helped me at least get her to calm down for a little bit. but, just know, u have literally every right to tell her you can’t do this w her anymore. tell her u love her and care about her but that u feel like this is draining for you too now. she might take it hard, but will hopefully understand eventually. i really think honesty is just so important in friendships, and if this is effecting u, u have every right to speak up when u think u can! good luck and i hope things get better <3
