Confused

Hello, my first time posting here or anything on reddit actually, lovely to meet you all, I’m 19M and my parents are narcs, I recently had an experience with my mother that has just shot me down, she yells at me for not getting a payment sorted because of a course I failed I got kicked out so I have to still pay the rest, I couldn’t tell her I failed of course because even though she SAYS that I can tell her anything, in the past whenever I tried to it always had a positive or negative outcome no matter what it is so that’s left me keeping quiet on matters, then she starts spitting nonsense at me that’s just not true and as she was saying what I apparently “am thinking” and “my mindset” none of it was accurate and FAR from the truth, I feel so alone, she doesn’t know me at all and neither does my dad but that’s a seperate story, after the argument she wanted to see my bank account and I kept denying her because I’m allowed to by law and she used the excuse of “your under my roof so everything is mine” which isn’t correct so I still didn’t show her, then she hugs me and completely contradicts everything she said to me that was hurtful with nice things and it’s left me so confused, I’m 99% sure she’s a narc just wanted to vent
