I don't know how to be a friend

I recently told a friend that the way she spoke to me when she was frustrated hurt my feelings and I know she didn't mean to hurt my feelings but I thought I should let her know. She had told me previously that we could tell each other anything that was bothering us.

I would say casual things and she would roll her eyes or shrug and not look up from her phone, just small things and I'm a highly sensitive person (I just left an abusive bf this year so I'm extra sensitive.)

Her response was to tell me our friendship was one-sided, I never do anything for her and that the world doesn't revolve around me and my problems. (I was trying to explain to her why I brought it up a day later over the phone, I can't really deal with any kind of confrontation right now without crying).

I was so hurt because she told me "EVERYONE is going through stuff."

She was one of my rocks earlier this year when I finally revealed what I was going through. I just feel shocked and depressed about the whole situation. It's been almost 2 months and she refuses to talk to me still, she told me she cannot trust me. I don't understand where it's coming from honestly..

When I asked her about repairing the rift, she told me I all we do is send each other stuff on TikTok and instagram so what kind of conversation would we need to be having now...

I thought we were close friends (I only have about 3) and she was confused that I thought we were close.

I guess I'm just wondering how real friends communicate and how often? What do people talk about? She's incredibly private so when I ask questions she gets suspicious so I try not to do that and I don't want our messages to be just me talking about myself all the time.
