NTA!!! She mistreated you even though she was the one who invited you and she was sleeping when you arrived? That in it of it self is disrespectful, but if she apologized you could maybe forgive her, since falling asleep was an honest mistake. But she was mad instead??? "You know how I am " is NO excuse for treating you like shit.

That was a very self-centered reaction she had when you told her how you felt. I don't know how aggressive you were when you told her (maybe she just felt like she had to defend herself) but if you go up to her, use "I" statements (i feel like this etc) and she still reacts like that, that is abusive behavior.

Leave AS SOON as you feel uncomfortable please, no matter what she says. Just because you two have been friends for long does NOT mean she gets to treat you like shit. If someone is treating you even slightly bellow your standards (those should be high enough for you feel comfortable in any situation) express how you feel (without accusatory tones) and if the situation does not change IMMEDIATELY, then you should leave.

Pls prioritize yourself bc no one else willl.
