Venting about best friend. Cuz I can’t deal.

Hey ladies. I know this group is probs about relationship relationships but I didn’t know where else to vent anonymously about this because I’m at the end of my rope. I’ve been friends with my best friend for like 7 years almost but we’ve known each other longer (our families our close). The first few years were great. We had fun and hung out a lot and talked all the time and all that. The last few years life has happened and it’s been a little rough for her. I am the optimist and usually it’s easy to get her encouraged. But she tends on the side of drama and attracts it and seems to actually enjoy it and I’m the opposite. I steer clear from drama and do not like it at all. She also is one to post EVERYTHING on social media to get attention and I just don’t get it. Anyways. I still try to pull her out of the negativity without coddling her like she’s looking for. I am always truthful and don’t tell her things just because they’re what she wants to hear. I tell her what needs to be said but try to do it gently. But man. After a few years of constantly having to pick her up and her not seeming to even want to stay standing I am drained. Completely drained. I’m so tired of every single text message being something wrong or something negative. I may be exaggerating a little on that but seriously when we have a convo there is always AT LEAST one negative thing she has to say and I’m exhausted. It’s to the point where when I see her name on my phone I 🙄 because I am like well I wonder what it is now. And usually I am right and it is negativity and drama. She has been through a lot in her life but hasn’t everyone? I love her. And do not want to not be there for her anymore because that’s not the friend I am but man. I am at a loss as to what to do. I have told her about this but it doesn’t ever seem to stop it or help much. She gets offended and slows the negativity a bit for a while but it usually just escalates slowly back to all the time again. Has anyone been through this and done something that helped? Venting helps for sure so thanks for that already. Lol.
