Should i help her or not get involved?

I havent talked to this old friend in years but ive noticed on social media shes going thru alot. She keeps having these ummm "break downs" and im wondering should i reach out and try to comfort her after what appears to be the end of a toxic bad relationship? Or should i not get involved? The ONLY reason i feel maybe i shouldnt get involved is because she seems to always have some sort of big drama going on especially with this guy and while i want to help.. i feel it wouldnt do much good and id just get sucked into the crazy drama that is her life.. i feel bad for her she does struggle with alot of mental illness.. which makes me want to help her even more but idk.. when i knew her back in the day she could be a really nice positive person but almost always was very negative.. i just want positivity i dont want to talk to her for a bit realize shes still ummm "a little much" and then her go off on social media rants about fake friends and people leaving her as shes been doing for awhile now :/ any advice? Please be kind with your words.. im trying to do the right thing but at the same time trying not to totally push her off the edge.. she wasnt totally unstable then but judging from social media lately she seems off her rocker..

I feel bad that im even hesitating to help, i just dont want to get pulled into her crazy mess of a life to be quite honest.
