I just am. Why? It isn’t making me feel any better

My neighbor told me some very blunt advice about people not liking me. I explained that this really cool girl that most people love hanging out with, she is funny, feisty, witty and very kind hearted. I mean this girl is fearless and seemed very cool to hang out with but the problem is, she looks uncomfortable when she’s around me. When I come in and some people say hey, she says NOTHING. She’ll move to the next room. She talks to my two best friends but she ignores me. When I tried to talk about my trip to the others (hopefully that girl will be interested in hearing it) she just walked out of the room on her phone. Whenever I come in, she leaves the room, when I talk, she seems very annoyed or ignores me.” I tried. It always fails so I gave up for a while. I asked my elderly neighbor and she said, “Okay I’m going to stop you right there. Stop trying to get this girl to like you. Stop trying to get her to do what she doesn’t want to do. That’s beings passive aggressive and you gotta stop that! This is important to know. To put it bluntly, not everyone is going to like you. Even though you didn’t do anything, there will be that someone that will be annoyed by you and will have opinions about you. You can’t make her like you so stop it. Young people have to realize and understand that not everyone is going to like you!!”
Her words offended me. I was like, “You know, you’re not really making me feel better. You’re making me feel worse.”
She laughed and said, “Who said I was? Heh, I wasn’t trying to make you feel better! I’m telling you all this because it’s the facts. You’re going to feel uncomfortable once in a while so you have to learn to accept that. Life isn’t about sunshine and rainbows. Get out of lala land.”
She sounds so rude sometimes. I don’t ask her for advice because she’s too blunt sometimes and points out stuff.
