AIO for kinda ending a 17 years friendship?

Hi im a 19F and my "bestfriend" who we will call Amy is a 23F and we have known eachother since i was 2 years old (we are neighbours).

Im sorry in advance if the post is all over the place i just dont know where to begin.

This has been going on for a long time but here are some Situations that happened:

We are walking together and im very excitedly telling her abt my day and she isn't paying attention at all , i stop mid word because this has happened countless times before , she doesnt even notice or say anything abt it and when she actually listens the only response i get is a "nice" or a "cool".

She is never happy for my accomplishment and when i mentioned that to her today over text(i will talk abt the text and her response later) she said me sharing my accomplishment and achievements is me trying to appear better than everyone and that i think im the best at everything and said this is a " narcissistic trait i have".

We see eachother almost daily, and this whole week i didn't see her or text her because i got food poisoning and was really sick she didnt even notice or like checked on me.

Over the last 5 years i talked to her many times abt all of this and everytime she agrees that im giving more energy and she says she will try more but she never did + she claims that she forgot all of the conversations we had.

Even like 2 weeks ago she was going through exams and stuff and was stressed and i told her hey there is something that is really annoying me i wanna talk to you abt but i will wait till you are feeling better, she never asked abt it.

She even said she is jealous that i went out with my another friend (she was invited and joined us too) even though i only see my other friend once in summer but i literally live 5 seconds away from her house.

She also said to me that im her idol and i explained to her that im just someone who works hard and anyone can achieve what im achieving , she kept asking me how i can think like that or understand that fast and how she wishes she could have my brain , i was like no love you dont wish you can have my brain.

Even as kids she took my imaginary character and made him her lover in a video game and later admitted it to me and i was like uhh that is weird but like you do you.

Another example i was learning spanish a while ago and she wasn't but she took some words from me that i ised to say a lot ("hola" "animales"....) and changed her whole social media captions and bio to spanish , it didnt bother me at the time but now when i think abt it im like yeah that is weird.

Many more situations happened but i guess i keep brushing them off because we were really not mature.

Another thing we planned to start a podcast like 3 months ago , we prepared everything and even bought equipment and through the whole 3 months every single time we talk abt the podcast i ask her if she is sure she wabts to do it and she keeps saying yes(i keep asking because she has given up on many projects we said we were gonna do before) so today she send a text " hey..so abt the podcast i dont want to do it anymore because i have a bad feeling abt it" , she is totally allowed to back out of it but not after we invested everything.

So i replied to her and told her that she can do what she wants but dont expect me to not be disappointed and i told her that i have another thing to tell her that is unrelated to the podcast.

I told her that the reason i distanced myself (what i meantioned in the post but like a summary)

Her response was: as you wish then again i explained everything in details she replies with "yeah okay whatever, this friendship is stressing me out and i see that both of us are tired so we should take a break".

She even gave the phone to her 36F sister to text me preting to be my friend and i caught on and told her to give her the phone back.

And she blamed her not caring and not listening to me on having a "medical condition" , she diagnosed herself and no she doesn't have a condition she says that abt everything she does.

I told my mom and my sister the whole situation (her family is my families bestfriends) and they told that since i was a kid amy has been jealous of everything i do.

After a lot of message I ended up telling her that if she wants to reach out i will happily respond and that im not gonna be the one reaching out anymore and im happy to take a break.

I can't completely cut her off because again our families are close and we are neighbours.

(This has happened with her sister and my sister and they are no longer friend , her sis didnt go to my sis wedding because she was jealous that my sis is giving her husband more attention than her and those are her words)

Anyways i just wanna know am i in the wrong here?
