How do I break up with a mentally unstable internet friend...?

HI^ So I've met this girl on discord. she's 14, and in 17 btw. she messaged me outta nowhere, and we became friends. we really didn't talk much, and I didn't really like her too...so i tryed to distance myself from her...

Later ive decided, that i just want to not be friends with her anymore, and messaged her saying that...i dont think that she rly cared, and told me she doesnt wanna talk to me, and that i should leave.

later the next day i started feeling bad, couse i was scared that she might do something to herself, couse i think she was sad for the longest time, and me leaving her would make her even more sad..so i messaged her again to ask how shes doing, and say sorry...i dont think she rly cared, and said that its ok. i felt bad so i said we can still talk if she wants to, she said ok, and that she doesnt want to talk rn, and that shell talk to me tomorow.

i rly dont wanna talk to her, we only talked couse she messaged me out of nowhere, and i rly didnt wanna be mean to her, and tell her to go away... but now i just cant keep pretending to be friends with this person...i guess we do have a lot in common, but i just rly dont like her, or wanna talk to her... please help me and give me advice how to deal with this situation... i just want to leave, bu also i dont want her to be sad...

next year is the final for me i highschool, and i wanna start a new life... so i rly wanted to just say bye to everyone i talked to over the internet.

(p.s THERE WAS NOTHING romantic netween us, or even suggestive. and we didnt like eachother. we just talked about teen stuff... like school, videogames, and other intrest like shows.)
